Photoshop_AI generative fill_reference image automatically detect and select wrong subjects

I encountered an issue while using Photoshop’s AI Generative Fill feature. I was trying to import a reference image to improve the generated result, but after importing the reference image, Photoshop automatically detected the subject and removed the parts I actually needed—usually leaving only the less important areas. For example, when I tried to use Generative Fill to insert a staircase into a landscape scene, I imported an ideal reference image, but without clicking anything, Photoshop auto-detected the subject and only retained half of a foreground figure in the image.

While there is an option to adjust the external reference, the available settings within the system couldn’t resolve my problem. I’d like to know how I can fix this.

I’ve used this function many times before without issue, following the exact same steps hundreds of times. Previously, there used to be an option to toggle automatic subject detection. I’m not sure if this has changed due to a recent update.(I currently using Beta 26.8 and not sure when the problem began)

Somebody helpppppppppppppp
