What's wrong with tiles?

Question

Already asked 2 times, no answers, ok, I'll ask again, what's wrong with the tiles? why in the palette they run into each other, and when the table, for example, it is simply attached to the middle of the cell, and not to the edge, please help
me on the first photo, on the second - a normal palette and everything is fine

Answer 1

Mystic. Did you try to reinstall the unit or recreate the project?

Answer 2

Change the default PPU
to 100 pixels per tile. If the tile is wider / narrower, then you need to adjust.
