### Steps to reproduce

I just discovered I had few space Ln the device, but I don't look at that often so if can be done time.

After investigation I saw nextcloud has synced directories I never would have told it to sync like an .img file.

I checked and I only have three directories in the "two way sync" which I have enabled some time before because I thought https://github.com/nextcloud/android/issues/13872 must be fixed now.

And indeed I see no data usage grow though, but well nextcloud going berserk anyway.

### Expected behaviour

Not sync directories I never wanted to sync.

### Actual behaviour

It synced as far as I see all of them.
