Race change bugged?

So I bought race change for 20 points, and when I tried to change, it brings me to a screen where i can change gender, name but not race. Races are gray and not responsive. > https://prnt.sc/hudub5 < > https://prnt.sc/huduum < > https://prnt.sc/hudvfe < - Lightshot screenshots.
I wanted to go from tauren to troll... any help?

ehm... Only Taurens can be Druids in Wotlk.
If you wanted to turn Troll that is on Cata
If you wanted to go Night elf you should have picked "faction change"

Welp, im ******ed. thanks for clearing that up
