Everything gets deleted

Hello everyone,

Since yesterday I got my wordpress hosting working and I got started with making my website immediately! I am using elementor to edit the pages and envato elements for a template.
I created a page, imported an envato element and starting editing it.
Then all of the sudden everything is gone. I didn’t know what to think of it, thought it was something on my end, and started over. Did the same thing, again everything suddenly disappeared around the same stage, not after doing the same thing. Then I decided to try it as a template, eventually everything got deleted again!

In the first two cases the page was directly coupled to my live homepage, so after making a change I would look at the website to see how it looks on the live version. This is how I would find out everything is gone, because it would be blank except for a footer. In the editor it was still there, until I refresh. I could still make changes and publish them but the live website would not show anything anymore.

Eventually I found the revisions button, on both pages and the 1 template you see in the revisions that all of the sudden everything gets deleted but I don’t understand why! Reversing it to that revision doesn’t work, it makes everything look weird and compact.

I have no clue what to do, I hope someone can help me out :/
