Shelly button1 only 2 channels after firmware update

After latest firmware update of a Shelly Button1 I get only 2 channels on OpenHAB (see screenshot). The Events channel (and others) are missing. Someone has seen this issue? Any idea how to solve it?

Shelly Button1 FW version is 20211004-121522/v1.11.5-gdedfb52
OpenHAB version is 3.1.0 stable

Thanks, Ondrej
