Decals not saving in file

Hello, I'm using SW Premium 2015

I'm trying to save decals inside the model file but it isn't working.  I have the store appearance, decal, and scene data checkbox checked but after I apply the decal to the part it is still showing the local path to the decal file, it doesn't say "Image Stored In, etc" that I've seen before when this feature worked.

This is what the image file path indicates after decal file was imported.

Any ideas in what is causing this issue?  I swear it's worked for me in the past but it seems to be an intermittent problem.
