Pine Script 5 - Unwanted alert messages - pine-script-v5

Question

I receive unwanted alert messages. I would like to have only 1 "Go Long" alert when going long and then no other "Go Long" alerts until after the first "Go Short" alert. I'm having trouble getting this right.
//#version=5
strategy("Single Alert Strategy", overlay=true)
// Create flags to avoid multiple Long signals when already in Long and multiple Short signals when already in Short
isLong = false // We initialize a value and give it false (we are not in a Long position)
isLong := nz(isLong[1]) // We check the previous value and assign the previous value to this variable (when no previous value exist it will become false)
isShort = false // We initialize a value and give it false (we are not in a Short position)
isShort := nz(isShort[1]) // We check the previous value and assign the previous value to this variable (when no previous value exist it will become false)
// Long Short conditions
tot_rsi = ta.rsi(close, 14)
bullLevel = 30
bearLevel = 70
longCondition = ta.crossover(tot_rsi, bullLevel) and not isLong // Go Long only if we are not already Long
shortCondition = ta.crossunder(tot_rsi, bearLevel) and not isShort // Go Short only if we are not already Short
// Change the flags to avoid duplicate signals
if (longCondition)
isLong := true
isShort := false
if (shortCondition)
isLong := false
isShort := true
if longCondition
strategy.entry('Long', strategy.long, alert_message = "GoLong")
if shortCondition
strategy.entry('Short', strategy.short, alert_message = "GoShort")
// Plot the signals and compare them with the Alerts log
plotshape(series=longCondition, title="Long", text="Long", style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)
plotshape(series=shortCondition, title="Short", text="Short", style=shape.triangledown, location=location.belowbar, color=color.red, size=size.small)
I followed the instructions in the answer provided here. While the signal indicators plot correctly (no additional signals), I do get an alert message when there was no signal plotted. This strategy is newly created with a new alert and is only added to 1 chart. The alert was created at 06:58, there were signals plotted before the alert was created but it triggered at 07:05 even though there was no signal plotted.
RSI level at 07:05 was 48.20
Any ideas what may have caused this alert to trigger and how to prevent additional alerts like these?

Edit: I'm testing an alternative approach. The unwanted alerts do not come frequently so I may have to run it for some time. If anyone knows of a different work around then I'm happy to give that a try.
//#version=5
strategy("Single Alert Strategy", overlay=true, calc_on_every_tick = true)
noOrder = strategy.closedtrades == 0 // There is no previous order
openLong = strategy.position_size > 0 // We are going Long
openShort = strategy.position_size < 0 // We are going Short
// Long Short conditions
tot_rsi = ta.rsi(close, 14)
bullLevel = 30
bearLevel = 70
longCondition = ta.crossover(tot_rsi, bullLevel) and (openShort[1] or noOrder) // Go Long only if the previous order was Short
shortCondition = ta.crossunder(tot_rsi, bearLevel) and (openLong[1] or noOrder) // Go Short only if the previous order was Long
if longCondition
strategy.entry('Long', strategy.long, alert_message = "GoLong")
if shortCondition
strategy.entry('Short', strategy.short, alert_message = "GoShort")
// Plot the signals and compare them with the Alerts log
plotshape(series=longCondition, title="Long", text="Long", style=shape.triangleup, location=location.belowbar, color=color.green, size=size.small)
plotshape(series=shortCondition, title="Short", text="Short", style=shape.triangledown, location=location.belowbar, color=color.red, size=size.small)
Edit 2: The 2nd approach also created an alert despite there not being any signal plotted. Screenhot here

You should test also with strategy.opentrades which will return something !=0 if a trade (Long or Short) is currently open :
if longCondition and strategy.opentrades==0
strategy.close_all(comment="close", immediately=true)
strategy.entry('Long', strategy.long, alert_message = "GoLong")
if shortCondition and strategy.opentrades==0
strategy.close_all(comment="close", immediately=true)
strategy.entry('Short', strategy.short, alert_message = "GoShort")
