Artificats showing up from old map

I am getting a bug where an old texture I made in Xnormal is appearing as an artifact in a new map. 

In the image I included- On the left is an old map that I made.  On the right side of the image is a new map I am making.  If you look at the blue normal map you can see the artifacts of the old map.  No matter what new map I make, I get the old image as an artifact on the new maps.  If anyone has a work around for this or run into this I would much appreciate a fix.  Thanks.

FYI- All geometry from the old model has been removed - I updated to the latest version of Xnormal.  I still get the same issue.
