I could not understand the exact issue.
Could you please confirm the version of Lightroom you are using?
Also, share your exact workflow steps including the expected outcome.
I'm using lightroom 4. When I click on heal or clone to remove a spot then click on the spot I want to replace it, it will go right back to the original spot I was trying to remove. I've been using this version for a while and all of a sudden today it will not work.
