refreshes each channel as you add or remove it.
6 To remove a channel from the Member List, select the channel in the
Member List and click >>.
Each channel must belong to a group. A channel can belong to only one
group at a time. You cannot move a channel from the members list to the
non-members list of a group unless the system can assign the channel to
another group. If a channel has never been a member of another group,
the system cannot determine a group to which it can move the channel,
so it cannot remove the channel from the member list. If a channel has
been a member of another group in the past, the system moves the
channel to the group of which the channel was most recently a member.

Example: By default, the system creates two groups, Group 1 and
Group 2, and places all channels in Group 1. If you try to move a channel
to the non-member list of Group 1, the operation fails. If you select
Group 2, click Membership, move a channel from the non-member list to
the member list, and then move the same channel back to the
non-member list, the operation succeeds because the channel was
previously a member of Group 1. If you then view the Group 1
membership list, it contains the channel you just removed from Group 2.
