HmIP-WRC6 only two channels in HA

Configuration
1

Hi,

i´m trying to get the HmIP-WRC6 working in HA. For some reason HA only sees two channels
Bildschirmfoto 2023-10-02 um 16.38.48
These channels work fine, but where are the remaining four channels?

I´ve also implemented https://github.com/danielperna84/custom_homematic#events-for-homematicip-devices
These two channels can trigger automations. The other 4 channels are missing. so if i hit the button, nothing happens.

best regards
