Spot Removal tool malfunctioning
[I am using Lightroom Classic CC 7.1]
The Spot Removal tool is usually pretty clutch. One one particular photo I am working on tonight, the tool is not working but ONLY on one particular spot (Photo 1).

I did a random spot removal on another area of the photo and it works fine (Photo 2).

I have never seen this issue in all my years in Lightroom and I have no clue what is going on. This tool always works awesome, even on bigger spots. Any thoughts?...
Thanks.
