Vanquish not recognised

So I today Vanquished Talmark Wilderness, got the HM enemy counter to go Gold and when clicked would say "You have vanquished all foes in the area", got about 980 XP and 980 gold yet the HM emblem in the map remained red and even after I zoned also remained red.

So having VQd it I will now need to VQ it again unless it is a bug.

Has this ever happened to anyone else and if so did you ever find out what caused it?

It's to do with War In Kryta. I found when I opened my map up it would be either red or gold.

If you vanquish the area again it'll turn the helmet gold fixing it. Though it doesn't matter for the title.
