Well, I had this problem and I think I found a solution to it, but I was only able to solve it with the full version of CM.
What I did was:
- In CM, go to Content / Tracks.
- Find the track you're having the issue.
- At the bottom, click on skins.
- Click on + create a new one (if you're not finding this option, just manually search for a random skin name and it will show up).
- Create a random skin, it will generate a new cm_skins folder in your track's skin folder.
-Transfer the skin you're having the issue to this new cm_skins folder.
This solved the problem for me.
