Dragonflight Season 2 Hero Appearances still not unlocking for me even over a year later

I’ve been pretty upset with this for well over a year now, I am not sure if anyone else is experiencing this issue. I had earned the Elite Gladiator Shoulders from DF Season 2 and they are probably my favorite mog piece, however, when I unlocked the 2500 reward item and used it the extra appearance for the shoulders did not show up and were still locked. In game it says “unlock base appearance to unlock this hero variant” which I had already did, I literally have the shoulders transmogged right now on my Mage.

Over the past year I have made multiple support tickets, bug reports on the forums. I did everything GMs told me to do and nothing has happened. This is literally a bug, I am not sure why its not fixed yet.

Here is what I put in my old bug report post:

"I had earned the entirety of the Elite PvP set appearances from Season 2 (For Mage), I also achieved 2500 io last season and had unlocked the alternative appearances for earning 2500.

For some reason though, the Elite PvP shoulders did not have its 2500 io appearance unlock after I earned Hero. It is still not fixed and I have been continually reporting it for months. I look at my transmog library and the base Elite PvP shoulders are unlocked but the alternative appearance is locked saying that I need to “unlock the base appearance” to unlock it…even though I already have it."

Any help would be appreciated.
