Mobile version shows deleted page

I don’t know of Corvid by Wix is the right place to ask, but I’m desperate and Wix doesn’t respond to my support request, despite upgrading my account a couple of times.

The design looks great, but what I experienced upon launch of my months-long project is either a really nasty bug, or just a major design flaw where I can’t figure out how to display this properly.

Basically it all looks great on desktop. And on tablets. But on mobile, it openly displays a password-protected page that I then also deleted. And it does this on every page on the site. I discovered now if I choose to get rid of the headers and footers, then it DOES show the actual page, although missing the first half or so of the content and the rest is formatted badly.

I have no idea how to fix this, but I trusted Wix to present my site on mobile properly, and this looks incredibly amateurish. A huge disappointment so now I just have to fix it the best I can.
