Automatic uploads something and delete it

Nextcloud version (17):
Operating system and version (Android 10):

Is this the first time you’ve seen this error? (Y/N): N

My nextcloud App for Android uploads automatically the Screenshots folder but I have not set a config that it should do it, so I can not disable that and every screenshot is uploaded and deletet automatically.
What can I do to fix it ?

Exclude it from the automatic upload (nextcloud sign grey and with a slash when deselected)

it is already deselected

Then I don’t know, because it works with my Android.
