We see the same in our environment. Here is some additional info and a related forums posting; let's see what we have in common.
Problem in setting permission of a document library of current page scopehttp://www.liferay.com/community/forums/-/message_boards/message/5789324
We are seeing the same Page-Scoped Permissions issue in our organizations for the Calendar, Messageboard, Document Library, Image Gallery and Web Content Display.
When a portlet scope is changed from Default to (Current Page), Organization roles and Teams become unavailable in the permissions dialog.
Steps to recreate:
Create a new Organization
Add a private page
Add a calendar portlet to the page
Look at the config-> permissions tab (you should see "Organization
Member", "Organization Administrator", "Org Owner", etc. as options)
On the Scope tab, change from "Default" to ".. (Current Page)" and
Press 'Save'.
In our environments, when we switch back to the permissions tab, we no
longer see "Organization Members" or the Organization Teams we have
defined.
Instead, we see "Community Member", "Community Adminstrator", "Community
Owner" and other community-roles instead.
Changing the scope back to "Default" makes the Organization roles and teams visible again in the permissions dialog.
We see this behavior for the page-scopeable portlets; Calendar, Message
Board, Document library, Image Gallery, ... and web content display.
We see the same behavior on both private and public pages in an organization.
I also added uniquely-named teams to every community to see if a specific community's roles/teams were being pulled in to the dialog during the error. I did not see any community teams listed along with the standard community roles. As a follow-up test, I tried the same exercise in Communities:
!
Default-scoped and Page-scoped portlets in Communities have a similar issue; both scopes show community roles in the Permissions dialog, However, scoping to the current page does not allow the user to view the Community's Teams.
