Inpainting/outpainting image and mask selection

Thank you for the greqt work by the way. I'm hoping you can help with a issue i've been having. Once i generate an image with the mask using inpainting : i'm having a really hard time to select another part of the image for inpainting. Like the button in the controlnet tab in which you can click in the button setcontrolnet image, the button to set the image in inpainting/outpainting does not work. It keeps selecting the first area i used for the first inpainting session. I have to restart photoshop every time. Maybe i'm missing some command to set the image after i selected it with the rectangular tool ? Thank you very much !
