Heiman remote - button press not registered

[WeirdBob]

Hi,
I added my Heiman 4 buttons remote, it's recognized and is using the zigbee button driver (developer: Smartthings, version 2022-10-04T19:46:44.366017992).
the device info are:

name: four-buttons-battery
label: HEIMAN Remote Control
deviceManufacturerCode: HEIMAN
deviceModel: SceneSwitch-EM-3.0
ocfDeviceType: x.com.st.d.remotecontroller

However when I press a button, the action is not triggered and there is no trace of the event in the event history.
logcat displays this:

Can you look into that? Thanks!
