Flight paths in Zereth Mortis bugged after faction change

Ever since I changed factions the flight paths in Zereth Mortis have been bugged. All of the ones we are supposed to have by default (World Boss island, Sepulcher one, all of the locus shift ones) now have green exclamation marks on them requiring me to click them. This wouldnt be a problem if half of them werent in locations you cant walk to.

I now cant unlock flying because the fps are unreachable and blizz support simply says “working as intended”
