Zoomroom Calendar Sync issues to Logi controller

My room calendar is confirmed synced and it's confirmed that my account is unaffected by EWS (uses EWS but is full delegate access) but I'm not able to get the calendar to sync to the room logi controller.  

I'm at a loss as to how to restore the convenience of the calendar being available in the room and any help would be sincerely appreciated.
