If 2 pvp zones overlap and you leave one and enter the second, then PVP Delay doesn't cancel and when it's over, the icon will show as PVE even though you're in a PVP zone. Like exiting the zone switches the Icon to PVE, but it doesn't check again if you're still in another PVP zone until you exit all PVP zones and re-enter.
If you leave one zone and enter another that overlaps it, the icon bugs
same here i get that and my zone are only on monuments
