[TS1001 (FB21-001) / _TYZB01_hww2py6b] Lidl got broken

What happened?

Now Z2M processes "I" button only.

{
    "action": "switch_scene",
    "action_scene": 0,
    "linkquality": 255
}

Other buttons produce no new State. I have 5 of them, it is not a HW issue of a single piece.

What did you expect to happen?

I expect it to work as before - reacting on all the buttons.

How to reproduce it (minimal and precise)

Press any key... :-D

Start with the FB21-001 Lidl device definition and reproduce the problem by pressing each button. Collect the missing database.db entry and debug log, then trace why only the I-button state is emitted. Done means all buttons produce the expected state messages again.
