[Other] Tileset issue/ Block issue

[CosmicBlazer]

I put a new gym in my rom but it is in the tileset 2 area for Pallet town. The reason I put this here is for easier use. However, the problem I am having is that it turns into a bunch of blank color boxes when I close out of it and reopen. (Like the attachment pic I put at the bottom) Is this because I replaced the old gym tiles with something from a map's tileset 2.

That happens if the 16 colours aren't exactly the same as those in the tileset.

I don't know how to put my point together since English isn't my native language, but maybe it's something about the palletes
