Sorry but there may be a mis-understanding. The Cover is the first row.

If you do not want this image on mobile you can just delete the row?
Originally i thought the issue was "Cover is disabled for phone"

Was applied but the cover behaviour was still there. Now everything is working fine no? the ROW exists but the cover behaviour does not.
" The cover will disappear underneath your content when you scroll down. A Cover is always browser filling."
Happy to help however i can Leo and reach a solution that you want.
Best wishes ✨
