Opentherm disappeared from Lovelace overview

Hi

I just upgraded everything of Home assistant.

I’m also using the Opentherm integration. In the sceenshot below, you can see some entities.
Before the upgrade, all these entities where shown in the area “CV” of my default Lovelace overview.
After the upgrade, I still have the area “CV” but the entities are no longer shown in the Lovelace overview. And the area “CV” is not hidden.
In history, I can still select the area “CV” and I can see all the entities and there states are changing/working.

I don’t see the area “CV” on my Lovelace overview anymore. If I move an OpenTherm entity in another area, this entity does not appear in the new area. But when I move something from another area, this works.

What should I do?
