[Error] Showing void instead of tiles when playing

[Email998]

Hi, I'm quite new to pokémon essentials and I'm working on my game. The problem I'm having with this map is that when I'm playtesting it, it shows void tiles only in a certain region of the map. Where the void is showing, there were a cliff with with a house and a lake on it made with the beach autotile. As you can see, I removed it all and put there simply grass but the problem is still present. Also I had "libpng warning: iCCP: known incorrect sRGB profile" warning when playtesting the game and other than the void tiles I'm showing you I had void tiles also in the small beach on the right of the map. This last issue seems gone since I've done some procedures to resolve the libpng warning (I just followed some guides online).
How can I fix this? Do you have any suggestion? Also, I wouldn't mind that much starting a new project from scratch because this is the first map.
Thank you in advance!

P.S. as I said, I'm really new to all of this, so if I made some mistake (for example, in "exporting" the map image from pokemon essentials or other things), sorry for that! feel free to tell me how to do it

Check your map configurations. This is probably because your map are settings is bigger than they should be.

Check also your maps connections in debug mode. This could be two maps in the same place. The wrong connection can make this bug sometimes.
