Previous Maps placed in Item Frames show newest Map when returning to the game

Previous maps that were created in the past in Item Frames change to the most current Map ever created when you return to your game.

Steps to reproduce
-Make a Map of your current location.
-Place it on the wall in Item Frame.
-Make a Map of a different region location.
-Place the new Map on the wall next to your previous map.
-Press home or standby button on your device.
-Return to your game and you will notice that both maps are now the same.

Keep in mind I did NOT upgrade any of the maps to show the pointer/cursor.
