Do you possibly have any idea why this happening?
The darker grass, that I really like, has a weird effect on any paint put on top of it.
Here you can see I used the same brush and did a circle. It just makes it hard to properly transition between paints.

Edit: For whatever reason, after I posted this I switched between some paints to see I can do it all on the lighter one and then it transfers perfectly to the dark one. Turns out, the dark one suddenly works normally XD
Another edit, It broke again and now only the textures below that one show up properly

I'm at this point considering deleting that level and hoping a new one fixes it.
