Backup app doesn't finish maintenance mode

Hi, I am running Nextcloud 23.0.2 on Ubuntu 20.04 as snap. I have recently installed the backup application and configured it in a way to run automatic backups at night as the server needs to be put into maintenance mode. However, the maintenance mode never gets disabled. I always need to log into the server and disable it manually.

Has anyone else ran into this problem? The perspective of doing automatic backups actually seemed quite promising.
