Photoshop 25.0.0.0 Generative fill leaves selection edges

Hi,

I have updated Photoshop to its latest version and when using Generative fill, there is a difference in color visible on the outside of the selection edges. See attached picture.

I used Photoshop Beta before this but got rid of it (uninstalled it) thinking that could be the reason of the problem.

I have also tried to change the color profile as this was suggested before in other posts but that did not solve the problem. 

Thanks in advance for your help.
