Wrapper Not Included in Sticky

Hello Again,

I hate to be a bother, but I ran into another issue and I was wondering how if it could be resolved. There’s a gray wrapper that’s behind the search bar, and I’ve also tried adding it to the CSS, although I can’t seem to get that gray background to stick with the search bar.

Again, any insight would be greatly appreciated!

Thanks,
