Rems unlinked from document

Yesterday I edited some cards while I was in the queue. I also marked some as ‘edit later’. Today, large parts of my documents are missing. When I look at the edit later view, I can see these (or at least some of the) missing parts. The top node of them is ‚Unnamed‘ in each case. Also, in my backups, the content of the missing parts are still there, but when i load the backup on a separate account, the documents do not get repaired (which makes sense because I made the backup with the malfunction). Has anybody else encountered anything like this? Did you find an easy solution?

Here is what it looks like:

This shoud read something like Doc title > Chapter > MinMax > Min max outline: > procedure.

I have the same issue. Take a look here.
Many users are having various issues since yesterday. At the moment developers didn’t reach to us about this.
