Map hidden after all town trips.

Anytime I go to town to empty my bags when I get back to an area the map is completely covered up like it’s my first time there. All my waypoints are there and I can use them, but the map is covered up. All the enemies are dead if I want to run around and re-clear the map there’s nothing to kill is dead. The map is just reset. This happens if I go to town to empty my bags and I’m there for five minutes or just open a portal step through it and take two seconds in town
