Greetings all, 
I’m very curious to if anyone else is experiencing this issue.
I’ve already contacted a GM and received a response just advising me to submit a bug, which I have done but will probably not hear anything back from that team.
Basically like the title, my progress towards the 90 Exalted Rep achievement is not tracking correctly in game. I am not dependent on any reps outside of one character, my Paladin Ryai, is who I have always completed rep grinds on, so logging other alts e.t.c. isn’t my issue.
I have the achievement for 80 exalted reps. When I click on the 90 exalted reps achievement the tracking bar incorrectly just says 18/90. It should say 83/90.
If I check my characters profile on Wowhead profiler it correctly shows 83 exalted reps.
Has anyone else had this happen? Did you complete a rep achievement once you maxed the required number regardless of how the ingame achievement is tracking your progress? Please, let me know. 
90 reputation achievement not accurately tracking progress
Hey everyone,
The tracker on certain reputation achievements seems to be a bit broken currently. This is being worked on currently and should be resolved in the near future.
The achievement will trigger if you reach the appropriate number of factions.
For example if you have the 80 Exalted Reputations, and the tracker shows some very low number (as with Ryai’s example above), if the character reaches the 90 Exalted Reputations then the achievement will be awarded.
