I’m having trouble with
my wix header. I removed the green wix header box on accident, left the web and came back hence i cannot undo. Now when I go to global section, click add header to page, I get the header that takes up half my website. I’ve atatched an image as refrence.
Have you tried clearing cache/refreshing? It’s definitely not meant to do that 
If this continues, I’d recommend reaching out to Customer Care
