Adobe FireFly Model 5 Not working like previous version of PS

I am experiencing significant issues with the Adobe Firefly Model 5 in Photoshop version 27.10. Compared to previous versions, the model’s performance has declined considerably. I prefer using the native model over partner models, as the latter often result in lower resolution and image displacement after generation. Additionally, I have noticed that the specific brightness tool I rely on is missing, and the current "Light" tool does not provide the same functionality or results. Could you please advise on how I can restore the previous behavior or locate these missing tools in the current version?
