Hi,
Please use Martin's driver latest version - download it from here :
https://raw.githubusercontent.com/martinkura-svk/Hubitat/main/Moes%20ZigBee%20Wall%20Switch
Note, that the driver name differs a bit - it is "Moes ZigBee Wall Switch 1/2/3-Gang"
It may be a good idea to delete the version that you are using at the moment to avoid further confusion.
After installing the driver from the link above, pair the switch once again to your Hubitat hub.
The new Zigbee pairing is obligatory, otherwise the individual gangs control will not work.
Good luck!
Update: the driver is now available for installation via HPM :
