Strange glitch with healing tools

Hello friends, I have a strange glitch, when I use the healing tools on the smart preview catalog, then I close catalog and open it again, dark green or black areas appear on random photos, when I move the healing tools by 1 pixel in any direction - they disappear, and randomly appear again on the picture after ne open.
Maybe somebody know how to fix it ?
