Can`t delete Monitor

Hello guys, i have a Problem with my Xibo. The Version is 1.6.2. When i click on delete Monitor i got an message that the Monitor is in a Group, but it isnt.

The licence is unchecked. What can i do to delete this Monitor?

Thx for Help


Apologies for the delay, it seems we missed your post.

We’d definitely recommend upgrade to 1.7.6 CMS (and clients). 1.6.2 is quite a old version now.

That being said, are certain that your display device is not assigned to any display group?
