Mitsubishi Kumo Station gods please help coming off fossil fuel back to heat pump prob

I have a ducted SVZ setup with Kumo Station newly setup and it will activate a hydrofoil in the duct per the temp specs I set. The Thermostats are the PAR40s and while on fossil fuel it switches to say fan, which I *think* is normal, once the backup fossil fuel heat call is satisfied the system stays on fan and doesnt return to normal heat pump mode and just stays on fan. I also can't change it on the remote so it is stuck there. I had to digitally remove the station just to regain control. I am totally stuck why it wont return to non-boost mode after. Any ideas what could be happening or that I didnt do? Thank you as always!
