Action Bar Bug

[Zogrim]

You see that grey remain of the original blizzard action bar above my dungeon finder button?
How do I get rid of it?
Having it since 4.0.1 and I'm using Bartender4 for my Action Bars. Is any1 else experiencing this?
I can't even click on the buttons below the line.

Type /fstack ingame and put your mouse over the bar and report back what it says. Also is your Bartender updated to the newest version?

Updated bartender several times after 4.0.1, didn't think that the bug is actually connected w/ it.
But apparently the new version fixed tat bug. Thanks for reminding me.
Problem solved, sir.
