openHab Beta Item update issue

Hey there,
I got suddenly a new issue. After a few days it isn’t possible to set Item over the “kacheln” (i don’t know how ist called in English) “quick short cuts”
If I tapped on the Icon I get this notification:

The Beta Version doesn’t work anymore but at the stable version. Maybe it’s now a bug in the Beta version.

Has someone an answer for that?

Have a nice one.
Tobi
