What did you do in Design Mode just before this started happening?

Add a Widget?
Change a Widget Settings or Properties?
What type of Widgets are on the Screen?

3

I have seen that before when more than 1 of same widget were on screen specifically ticket lister. And they are configured a specific way.

4

I tried to make some edits to the CHAT Display. This started just after I upgraded to 5.1.61.

EDIT: I noticed there were duplicated entity screens. After deleting one of the screens it seemed to solve the issue.

Thank you guys very much for your help.

We won’t allow duplicate entity screen names on next update.
