So I think what you mean here is that it's not the item which remains on the map, but the map record of it? If so then yeah that's normal behavior--there was no time spent there after your turn (which wasn't even completed there), so it is not updated.
Logically speaking you could say it should be removed, but that's not how the map memory updating works, and it can sometimes still contain items that through various means you might technically have meta knowledge indicating that they no longer exist, or were moved somehow.
