Description

Tracking issue for:

• [bug] Entity/activity removed from a group via UI reappears after a reboot feature-and-bug-tracker#166

I could reproduce it, reboot is not even required: after removing the last entity in the group and closing the edit group dialog, the entity is still shown on the main page.

If the entity is removed with the web-configurator, it is no longer in the group.

How to Reproduce

See referenced issue

Expected behavior

Entity is removed from group

UI version

0.36.0
