Nagrand Slam

Greetings, I have been attempting to complete Loremaster these last few months, and I have run into a problem. After completing 75 out 75 quests in Nagrand I have still not been able to gain the Nagrand Slam Achievement. I tried to resolved this with a GM, but have been told twice that there is 11 quests available and to go check wowhead. That is how many quest I would have if I was Horde. I'm Alliance and WE KEEP TRYING. With the 500 character limit, however, I have been unable to express my case fully. Here is a list of everything I have done.

This leaves the Loremaster achievement out of reach to me, it is painful to think all that effort with go to waste due misunderstanding. Any help would be appreciated.
