Elementor created/edited content gone

Hello all,

I’ve noticed that the Sydney theme suddenly looks different from before, and I’m not sure why. Everything seemed fine previously, but now some elements appear changed or misplaced. The main problem is that our backups don’t fix this. It’s difficult for me to determine whether this change comes from the theme or the framework. We’re missing the “block” with the by filter selectable fotos and the blog. Maybe one of the automatic Elementor updates causes this issue but I don’t know how to get this undone.

Has anyone else experienced this, or could anyone suggest what might have caused it? Any guidance would be really appreciated!

Thanks in advance.
