is my list of dungeons available in the finder normal?

I just turned level 76 and the list of dungeons in my dungeon finder changed. It used to have a lot of options and now it decreased to the list shown in the image i uploaded here:

I'm just wondering if that's the way it should be right now. Does the list of dungeons change again at level 80?

Maybe you still had the Outland dungeons listed there that were green until level 75 so when you hit lvl 76 they were removed.
Dungeon list will only keep expanding from now on.
