Hi. I want to make a 4-channel freezer bunny pattern, but I don't know how to make the eyes and mouth non-recolorable.

I made my pattern in gimp and exported by color. I tried using the cap tool first, placing the face layer at the very top and disabling recoloring. It looks good when I test it in the casp 3d room, but the pattern looks wonky in the actual game. The colors were super off and when I changed one color it somehow affected the rest, including the face. Then I looked into delphy's pattern tool but there's no option to make the layer an overlay. I also followed gruesim's tutorial for converting patterns to packages so I don't know if I messed something up through that. Can someone have a look at the pattern and help me with this?

I attached the test package and an image of what it's supposed to look like
