My Campaign for Lemix Seems Broken.

So earlier on today I started on my Legion Remix Campaign for the broken shore. I did the Cathedral dungeon (like it told me to) on M0. I handed the quest in to Khadgar and he didn't give me another so I assumed no more from him, did my legion assault for the other lad, expected another quest from her, but nothing. I have no more quests for broken shore, but I definitely do as its not done. i check my map and quest log, and it says I need to complete my order hall campaign. The quest log for my order hall campaign says to complete champions of legion fall in broken shore to continue. What do I do now, and if its broken, how do I fix it?
