There is a problem with buildings when I place them on a new map

I just made my first map on Tiled and didn’t have any major problems with it. I created my second map and am using the same exact tileset. I don’t think I changed any settings but on this new map, when I place a building, it is discombobulated and its shadow is checkered. It looks really bad. Does anyone know what the problem is? Unfortunately I’m not patient or smart enough to problem solve it myself. Here is a picture of map one, and here is a picture of map two with the building problem. Thank you in advance.

Your second map’s tile size is smaller than the tiles, so the tiles are overlapping. You can fix your map’s tile size in Map > Map Properties.

Thank you so much!!!
