Marked as inactive while I collected everything within Frenzyheart Tribes but it says it's incomplete. This happened after reinstalling ATT, it worked before but probably because it saw I got exalted with them.

What is the missing thing in the Frenzyheart Tribe? Can you open it in the list or there's nothing inside? What do you see when you right-click the Frenzyheart Tribe?

Looks like the Outdoor Zones section of the Factions being listed has an issue. Under the 'Factions' category it properly shows as "Collected*" by having the achievement. I'll investigate real quick...

There is nothing there.
