Hello! - my light groups are broken!

Hello! - I've been using home assistant for a few months now, it was previously working great but now my light groups have broken

when using a button card to toggle a light group, it now seems to get stuck only being able to switch them on or off

weirdly I can change the brightness but the cards still detect my light group as off
