Alright, using the “OpenEMR 6.0.0 Main Demo” which you can find at
There are these users in the database:
Out of those users, admin (Billy Smith), clinician (Fred Stone), nap1957 (Nigel Pool) and physician (Donna Lee) are the only users who have calendar access. This is the insurance numbers page which you have mentioned above:
As you can see, only the users with a checkmark in calendar are listed in the insurance numbers page.
Only those users will have an appointment schedule in the calendar.
This should be the behavior or your own installation.
Cheers
