Hi,
I am trying to restrict users/group for a calendar in one of the spaces in my confluence. I don't think it is working. I have an admin and a test account as well. I have been testing by restricting the test account but I don't think it is doing what it's supposed to. The test account is still able to edit and view the calendar and events. Is anyone else having this issue with their confluence calendar? Please help 
I am using Confluence 6.4.3
Screenshots attached


Thanks,
Shark
