All maps in the game have the same texture in inventory / hotbar

All maps in the game have the same texture as the filled map as each map has a different texture or color on the map

To reproduce:

1. Get either empty map or empty locator map, and make them filled maps. their textures are intentionally the same.
2. Now, get A ocean, treasure and woodland explorer maps and notice how their textures are the same as the filled maps.

Expected results:
The ocean, treasure and woodland explorer maps have unique and different textures from the normal filled maps.

Actual results:
They all share the same texture as the filled map.
