Came to post this exact thing, it just happened to me. Did a couple intro missions for her, expecting to get her "A Path Into Darkness" arc. Got this instead.

I'm also having this same issue - makes running missions interesting as I have no idea what the objective is.

This happened to me too except it is 'the Path into Darkness Arc' for me.  Considering I get the P string in all of the in mission text, I'm curious about the Souvenir at the end.
