Messed up notebooks

1.0.241 prod linux

I am having problems with notebooks:

using Android, notes move from one notebook to another, without my authorization

For example notebook A contains note a1 and notebook B contains note b1. Then looking for note a1 with the search engine, I found it in notebook B and in notebook A there is note b1.

How are these notes wandering as they like?

Also trying to check the same stuff in the synced desktop version, entering each notebook I cannot see the list of notes. I just see the content of one of the notes already opened. So practically only that open note is accessible. But close to the notebook there is written (25) meaning there are other 24 notes in that notebook. But how do I see them?

So it seems something is wrong.
