How to change Cubmasters

I am unable to change or add a Cubmaster. I had two people in this calling, but when I try to add another one, "Cubmaster" is not one of the picks in the standard calling list. The only option is "Cub Scout Committee Member". When I released one of the existing Cubmasters and tried to put another ward member in that calling, I could select the ward member, but when I hit "Save" it still says, "Calling Vacant".

Is this just happening to me?

Note that I had to add "Cubmaster" as a New Custom Calling before I could give another ward member that calling. Now I have both a "Cubmaster" and a "* Cubmaster" custom calling.

I'm looking in LCR and see Cubmaster as a standard calling under Primary > Cub Scouts. I can't seem to add more than one Cubmaster, though. That's probably why Cubmaster is not one of the picks on the list.
