Members of a role display when doing the following steps:
Display the members of a Role.
After waiting some time, go out of the role and back in to redisplay the members. The membership table is blank.
The users have not actually lost membership in the role This is only an issue with the table display.
Adding a member to the role, even one that is already a member, and saving the role will cause all the members to reappear on the page.
