No paring of new devices of same model type

Configuration Zigbee
1

Hi all,

I am currently having a rough time paring new devices to my HA Add-On Zigbee2mqtt v1.18.1-1.
I am using 3x temperature sensors from XIAOMI (Xiaomi WSDCGQ11LM control via MQTT | Zigbee2MQTT). The paring itself is working smoothly, but what puzzles me is the following:
Only one of the 3 sensors can be paired at the same time.
→ If I pair the first one, it gets paired and displayed in the frontend
→ If I pair the second one, nothing happens (even in the logs)
→ If I remove the first one and pair the second one, it gets paired and displayed in the frontend
→ IEEEs and friendly names are different for all 3 sensors
→ batteries were changed and do not change the matter
→ the zigbee2mqtt log keeps quiet and does not log anything when pairing a second sensor

In the Add-On log there are no errors and just warnings for my devices which left the network.
Has something like that happened to anyone yet or could someone brainstorm with me?

Thanks and best regards

Uninstalling and reinstalling the add-on as well as re-pairing all previously existing devices did the trick. Now I could successfully pair all of my temp sensors.
I also tried the pairing at a shorter distance to the coordinator. I did this also before reinstalling the add-on but to no avail.
All devices and configurations can be backuped, but I wanted to be safe and just repaired all of them as well as reconfigured the whole add-on from the scratch.

At first, the existing cards could not identify the identically named entities. After I created a new card like a button for a light card with the exact same entity used in my existing cards, the existing cards could now address the entity again.
