When ever I change the color of any layer, it changes all of the layers to the same color I changed that one layer to, but also puts EVERYTHING in layer 6. (for example, the tiles on layer four will still interact with meatboy, but they are darkened to look like they are in the background, making it so there is no way to tell the difference between back tiles and active tiles.) I've also noticed that even if I change the layer back to its original settings, everything is still in layer 6. So this is obviously a bug.
I was just curious if I could get any help on this.

And I've already tried reinstalling it, which didn't work.
