New tiles in tileset are not appearing

Godot Version

4.3

Question

in godot 4.3, I have a TileMapLayer with a tileset with a texture
it works fine, but when I add a new tile to the texture, go into the TileSet editor and click the tile, the tile appears in the editor, but when I play in the actual game the tile doesn’t show, and is instead just completely transparent
this seems to happen with every new tile I add, while all of the tiles which were already in the texture work completely fine
I’ve tried reimporting the texture and deleting the .godot folder many times, but nothing works
