In addition to Ashley's suggestion Tim, from your image it looks like you've removed the title and any top tab elements and it lines up perfectly with your left pane tab.

The varying colors seems to call attention to any difference - example using default player:

If I change the left pane to match the main background, it makes a bit more sense:

Player Properties > Colors & Effects > Advanced Color Editing > Base (Main Background/Left Pane Background)

Hopefully one of these will be able to assist you :)
