"A New Frontier" Bugged

I have had 2 classes at 75 for a while and this title mission will not update. I try talking to Lachesis as it says in the description and she does not update anything.

I have 5 classes at 75 1 I reached after the mission became available and still will not complete it when I talk to the person

@Essadis911 take a look here...there is a user who posted a really good theory as to what is causing this.
