Nextcloud 10 tasks app only synchronizes "personal" list with Android Tasks app

Nextcloud 10 tasks app only synchronizes “personal” list with Android Tasks app. I would like my other lists to synchronize too. Is this a known limitation or am i missing something? Everything works fine in that list with added tasks. Any other lists stay either in nextcloud or local within the Android app.

It seems this only happens with OpenTasks app and not CalDAV TaskSync.

Actually it might be an issue with DAVdroid. After I deleted my account and recreated it the new lists showed up.
