Powershell Get-Date comparison is prevent an output - powershell

Question

I'm writing a script that I can run once every two weeks to clear out folders and files that haven't been accessed in two weeks or longer. I've written most of the script, and it works well until I add the following line of code:
Where-Object { $_.LastAccessTime –lt $RefDate } |
For some reason, this code prevents $condition from having an output [see code below].
I use $condition later in a do-while to recursively delete folders, but it won't loop due to this, or export the data to a CSV folder anymore. [Removing this line lets it work again]
Here's the key sections that the line is used in/relevant to it:
$dPath = "C:\Users\my.name\Desktop\PowTest2\*\"
$RefDate = (Get-Date).AddHours(-1);
$condition = Get-ChildItem $dPath -recurse -force |
Where-Object { $_.LastAccessTime –lt $RefDate } |
Where-Object {$_.PSIsContainer -eq $True} |
Where-Object{$_.GetFileSystemInfos().Count -eq 0} |
select FullName
write-output $RefDate;
write-output $condition
Above, $RefDate outputs as expected, $condition outputs nothing unless I remove the problematic line of code.
Edit:
Hi all,
Olaf made a good point, and asked me to check if the property is tracked for the folder. It appears it isn't, which would explain my issue. I'll update after more research and testing.

Not sure if its been answered, but i was doing some reasearch and found a 7 month old post where it was answered, i changed it around to match what youd like "It deletes all files older than 13 days, so not sure if that works lol". Let me know if this help
