Applying the world map creates holes in the world map and it's messy. Since it's Android 13, you need to change the file extension to mcworld and apply the world map. Worldmaps with small capacity do not, but when they are slightly larger, it becomes so. This bug is urgently needed to be fixed, so please fix it quickly.

The photo shows the normal world map, and the video shows the messed up world map when applied.
