IMHO, this is one of the wickedest "shots in the knee" by WGT:
In Olde Times, any owner could edit the CC notice and notices.
Then, "officer" rights were installed, and at that moment owner's rights were hurt. They can't edit these messages on their own right. They are excluded from edit rights unless any other member group is included in "Update Club Messages".
Thus, CC owners can only edit the CC messages after they give these rights to "officers", and a different officer is only available from CC level 2.
Thank you NOT WGT for excluding L1 owners from CC message editing!
