I use this tool mostly on a daily basis. I have a document ready (400x200px) to insert new layers every day and have it generate assets. After I updated PS to 25.9.1 the Image assets generator decides by itself to change randomly the height on some of my assets, despite all layers having the same height, and pixels to cover the already mentione dimensions. This is a recent issue. Sometimes I have to generate 250 assets of the same size per day, and I cant check them individually to verify the correct dimensions.
