Cannot setup organization with multiple owners on GitHub organization

I am an admin of https://github.com/wildgums and I am trying to add this organization. However, it keeps asking me for a login. While checking the requests, I see this:

{“errors”:[{“msg”:“User is not admin of the ALM organization”}]}

I just double checked and am part of the “owners” group in GitHub. Note that this is the first organization where there are multiple owners (the other ones I added so far only have a single owner (me)).

Anything specific I need to do?

Please see original post here, but got not response:
