" Witness of the Kirin Tor" title only for Alliance players?

[Vhx-black-dragonflight]

"Witness of the Kirin Tor" title not given

After completing the “Fate of the Kirin Tor” achievement, the title reward “Witness of the Kirin Tor” is not given. I have tried relogging, switching chars, fully closing game and relaunching, nada. Edit: My alliance chars have the title, but not my horde chars, not even the one that actually completed the questline/achievement
