BUG in Archicad 22 - Stair winders

[Jordan]

I am unable to select the stair winder settings in Archicad 22 (please see attached video). The menu drops down but I cannot select any of the options. This must be a bug. I have also tried on other macs around the office with the same issue all running os Big Sur. The one mac running Mojave works as intended.

sorry if this isn't the place for this 'bug report' I'm not sure where else to post it.

2017 iMac - macOS Big Sur version 11.6.8

Archicad 22 solo

Thanks,

Jordan
