Player showing up multiple times on adjacent maps

What I expected to happen was...:
Placing multiple maps in adjacent item frames to only show the player's location once, not in the corners of each map they aren't currently in.

What actually happened was...:

Steps to Reproduce:
1. Make multiple maps and stick em next to eachother on a wall
2. Be alive and in one of the maps
3. See multiple "player-arrows" for only 1 player.
