Image Occlusion - typing M (merge) A (add)

Whenever I press M to merge multiple image occlusion boxes, the letter is typed into my rem (to the right of the image). The same happens with A. Now I have the letters “a” and “m” all over my knowledge base because I didn’t know it was happening for a while. Any ideas how to fix it?
