Problem with Shared Calendar

Hi., I have one problem with the calendar: if I want to see the shared calendar with all the users I can view it only one user by one, I have already try to deselect “Shared Calendar Separate”
How could I view the calendars of all user merged in the shared calendar?
My version of SuiteCRM is 7.11.7.

In the calendar (month view for example) click “User list”.

Select more than one user with ctrl-click.

It works, thank you
