Problems with randomly copied folders of nextcloud

Describe the bug
Hello,

I had installed Carnet from F-Droid yesterday and linked it to my Nextcloud from Hetzner via Nextcloud app (Android 12).
While I was creating my first notes, a test picture and a test voice memo, I could see that Carnet synced some folders of my Nextcloud, which I did not select at all. To test, I created an extra folder and deleted the old one. Same problem. For me it was not obvious why Carnet simply copies other folders from my cloud. Private data was then even uploaded from my private nextcloud to carnet.live's nextcloud. o_O

Later I even created an account at carnet.live to bypass the syncs of my Nextcloud. Did not work apparently, because: It got really bad today when Carnet just burned/upload 30GB of data through my mobile data while I was out of the house, without me noticing it.
I have no idea why carnet duplicates other folders of the nextcloud, which did not appear as subfolders at carnet...

I deinstalled the app then, afraid it could happen again.
