Cannot register with my guild on Warcraft Logs

An officer in our guild setup the Warcraft Logs early on, I was given an invite code and joined it, it said I am connected with the guild and I just left it at that, as I didn’t need it for anything.

This weekend the officer in question was unable to raid, so I was going to log the raid, however I only had access to upload to my personal log. When checking logs previously I just searched the guild name in Warcraft Logs and viewed it that way.

I got a new invite code today and trying to input it I get the error “You are already a member of this guild” but looking at the logs I can only see Personal Logs again. We tried inviting other members into the logs and they get the same issue, they can see Personal Logs but nothing from the guild and they get the error “You are already a member of this guild”

Any idea how to resolve this issue?
