Level editor theme error.

[Magiolo]

WTF. My interface edges are blue, while the grid itself is black! If you change the theme, the edges will remain blue! Only the grid changes! This happened after I opened a resource of someone's level - the interface became mixed. How to fix it? I have already restarted the level editor. It doesn't help. What the hell.
