Challenges and unlockables

I explored the South Coast without having the Fnix rising expasion and discovered every Fnix outpost (I think)
I only bought the expansion today.
One of the new challenges requires to find 5 Fnix Outposts.
So basically because of my early exploring, having everything already discovered I can´t unlock it, and have to wait for new Fnix outposts to be introduced in new revamp areas to unlock it right ?
