Following the comments, I have tried to take account of the remarks and at first I cloned (in the buffer), the right edge in order to cut off the right part of unwanted, cut off the part flush with the black panel and added to the left of the field to have the same format.
I cloned the edge with the black border to bring it up to the extreme left, and then I tweaked the buffer to harmonize the background.
