Mine all have clear as well (mixture of Hue and Xiaomi), so the one with true seems to be the odd one. Can you post code of both? How do they look in the “Current entities” list?
I think you are using a virtual sensor for one and not for to the other sensor. That’s the reason you get no state info when changing from ‘state’ to ‘presence’. Set them both to the corresponding sensor ID (look for presence) as given in the CLIP API Debugger.
