Camp at the old village. (Assassin's Creed: Origins)

Hi all. Everyone knows that today is the day of release Invisible. Well, in General, have splurged a little and got it, so how did you clear the campaign and already bored of the game was. And the first thing that I confused is the fact that opening the map in the upper location had a completed icon of the area where you had to collect treasure, even though I never was at all... it's very strange. Anyone have the same thing? I decided to walk to this icon and see if there's some sort of chest or something, but nothing appeared.
