Why do duplicated hover elements reset to the original images every time I launch the editor or site, even after changing them?

I started using the Wix Studio recently and I have to say I’m very very disappointed. But I’ll try to focus on one really irritating issue:

I built one hover card, then duplicated it 3 times and changed the images. But when I’m launching the editor or hit publish the removed images displays again.

Really seems like a bug. Any idea how to fix this?
