Removing Power Lines - Residual White Line Removal
Hi all! I use Lightroom (Android app) regularly for photo editing and when I have power lines in my photos that I want to remove, it seems that about 50% of the time when using the delete tools (delete / restore / clone - using the app in another language so hopefully those are approximately the titles in English), I am left with a white line in the place of the power wire that is impossible to remove no matter what I try. The other 50% of the time, the lines are removed with no issue. I am attaching the most recent photo this is happening with here - please note the line left from a power line in the top third of the image. Any thoughts on how to address this would be much appreciated!
