XF 1.5 help! strange graphics on forum header, don't know what I did!!

[zoldos]

I'm not sure what I did, but after tinkering with the navigation template (and later reverting what I did), I now get this elongated "bar" on the far left and far right of my header nav and it expands PAST the page width. It's really bugging me, and no matter I do, I can't remove it. I've inspected console, checked multiple templates and CSS, and I just can't get rid of it! I use [cXF] Sticky Navigation 3.7.3 and when I scroll down, the strange bar disappears, so it has to be a simple code issue. Please see screenshot.

Please help! Thanks!
