Never heard of this bug before.
You may need to find a saved game before Jolee enters your party and redo the Shadowlands again and see if it will correct itself. I suggest do it with your mods. If it keeps doing it, then it's something in your override folder.
To quickly eliminate that as a problem; as soon as you get Jolee, go back to the Ebon Hawk and see if that works. You can even warp there so you don't have to wait exploring since you can't warp back to the Ebon Hawk from there and check:
"warp ebo_m12aa" (without quotes)
