Header Appears Twice

Hi,

I’ve read other posts about this. None of the suggestions helped.

There are currently 5 tabs on my menu. When I try to add a 6th, it looks fine at first. however, whenever a menu tab is clicked on, the menu starts showing a double menu. I’ll add a link to my page, but it is currently working. I didn’t add the 6th tab because the site is live and I don’t want the double menu showing up.

The page I need help with: [log in to see the link]
