After upgrading to core-2021.6.* Zigbee curtains greyed out

Dear community,

I am having issues with my Xiaomi curtains (over Zigbee2MQTT) in home assistant. After upgrading to 2021.6.* they are greyed out in the entities as well as in the back-end.

In Zigbee2MQTT configuration fronted they are fully operational. Other MQTT entities are fine.

Re-pairing them doesn’t help. Rolling back to 2021.5. seems the only way to solve this. Any thoughts on resolving this?

Hope anyone has an idea.

Best,
