Texture getting added to terrain when profile is generated

[dsolakk]

When I create a new GTS profile and add it to my terrain, I get an unknown texture overlaid on certain parts of the terrain, even with none of the profile settings enabled. 

I tried respawning my textures and reverting/updating my layer palette. But I get the same results. I also can't paint over the texture.

Do you know what might be causing this and how I can fix it?

Honestly not sure, it almost looks like snow coming from GTS.
