Danfoss Ally eTRVs: Strange config page differences, no more OTA?

Hi all, at home I am using several Danfoss Ally eTRVs (0100) which I connected to my HomeAssistant installation (Rasbian+Docker container, Conbee II, ZHA).
It looks like the latest HA version (2024.10.4) includes some changes when looking at the detail page for each device. What is confusing is that the page looks different for some of my devices despite being the same model (see screenshots below).
Any idea what went wrong here?

Also, zigbee-OTA/images/Danfoss at master · Koenkk/zigbee-OTA · GitHub lists new Firmware files, which I copied to my OTA folder, but I cannot trigger any update. Is it possible that the otau_directory setting in configuration.yaml is ignored?

You need to remove devices from network and add them once again.
