Nested group membership query returns old inherited group memberships

A user is member of a child group.
The child group is member of a parent group, so the user is automatically a member of the parent group.
When the user is removed from the child group, it should be automatically removed from the parent group, but a query for the group memberships of the parent group in an Identity Manager policy rule still returns the user.

Steps to duplicate:
1. Create a normal group "group1"
2. Created a nested group "nested1" which contains nested group"nested11" which
in turn contains nested group "nested111"
3. Create a user "user1"
4. Make user1 a member of group1 and nested111
5. Check the group membership of user1 in iManager or ConsoleOne: user1 is member of
all 4 groups
6. Check the group membership of user1 in iMonitor: user1 is member of all 4 groups
7. Remove user1 from the group members of nested111
8. Check the group membership of user1 in iManager or ConsoleOne: user1 is only member of group1
9. Check the group membership of user1 in iMonitor: user1 is member of group1
and also still member of nested1 and nested11 (flag ="Present")
10. After a while, the nested1 and nested11 on user1 are cleaned up
