Unable to post on the forums with my WotLK character

I’m posting this on the forums, because I was unable to get support through the CSR channels. My character for whatever reason on WotLK is unavailable. It is the only character I cloned from vanilla days and now, just recently, I can only post using my vanilla character’s avatar. The WotLK level 80 version of this character doesn’t show up in my option of characters to select.

So far, I have logged out of every device, played multiple characters on this account, have forced a password reset, and have been trouble shooting this with CSR for 10 days with no solution yet.

I’m wondering if anyone else who has done a character clone has experienced something like this and if they were able to fix it?

Edit: ANY UPDATES? It’s been 4 months!
