trying to place tiles using tile maps my tiles not lining up spaced out

Hello i'm trying to place tiles from the free unity tile starter kit onto my grid using tile map and the tiles are not at the right height it looks like. They are not lined up next to each other but have a space between them. I was trying to follow the unity tile map tutorial and i'm not sure what is wrong my settings look the same. I have a custom axis grid x0 y1 z0 and a tile palette with isometric grid cell size man x1 y0.5 z0. even if i do an isometric z as y or us other tile assets from Kenny i still get the same result. Any suggestions would be much appreciated thanks.
