Problems Leaving Club

Hi, I left a club I owned titled 'AmateurGamers', with the club tag 'AAGC' a while ago and created a new one titled 'AnAmateurGamingCompany'. When I got to five members, I tried to use the tag 'AAGC', but it wouldn't let me because it had already been taken. I asked my friend, who was still in the original 'AmateurGamers' club who owned the club. Apparently, it says I'm still the owner of the 'AmateurGamers' club. I am not in the 'AmateurGamers' club anymore, and can't see it in my clubs tab.

I would very much like to use the 'AAGC' club tag, but I can't without deleting the original club. How is that possible if I am not able to see the club in my clubs tab?

I tried to explain this as clearly as possible, but if you need to ask questions, please feel free to ask as many as you'd like.

Thank you
