Not sure, but this may be related to the improvements they have been rolling out. Show/hide seems to have been a major issue. I suggest you report it here:
https://www.wix.com/corvid/forum/community-discussion/rolling-out-improvements-to-corvid-sites-rendering
Note however, that (I think) they just switch your site back to the old rendering method so your site will not reap the benefits of the improvements for the time being.
They haven’t really been transparent on the issues either unfortunately. I had a similar issue with show/hide and reported it, they switched me back (site went back to being slower in some aspects), but I encountered another bug and they said that my site was probably corrupt, I duplicated the site which resolved the issue and the duplicated site loaded faster and didn’t have the issues with show/hide anymore.
