Google Assistant ignores FanSpeed, Toggles traits on Thermostat - actions-on-google

Question

I have a thermostat, which has capabilities of
Setting temperature. Works through Home app.
Setting thermostat mode. Works through Home app.
Setting fan speed. Does not work. Google Assistant ignores setting the fan speed and just shows results from regular Google search
Setting horizontal swing toggle. Google Assistant ignores it, same as above.
According to https://developers.google.com/actions/smarthome/tools/validator/ my Sync response should be correct. Below is an example of my sync response.

Why is it not working and what can I do about it? I also tried using AC_UNIT, but FanSpeed and Toggles still do not seem to have any effect.
