Grid lines in tile map after i uploaded to unity

So ive had anti-aliasing off to begin with, so i dont believe that is it. when i padded the tiles and changed a section of them they had just added the section next to them i believe. I am not sure where on tiled the borders can be applied as well?

So then i tried running the command for the Quick Hack: Tucking in Tile Texture Coordinates.

but this resulted in errors

Thank you btw for getting back to me so quickly, sorry i am very new at this but i really enjoy the platform!
