Not sure what you are asking. Could you please provide a screenshot? When changing clothes and colour of clothes, you may need to finese the image a bit. Meaning you may have to take it to Express and clean up the image a bit.
Thank you for your message. I am sorry you are having this problem.
In addition to what @Oh.N8 said, if you are having problems in Firefly Generative Fill, save the file using the Download button in the upper right corner to save your image with any changes you made selecting "Keep".
If you have to reset your session and were able to save the image, you can resume with that image.
