How to fix these two issues?

After importing Aseprite sprites to Unity, it offsets the whole sprite in Sprite Editor around 4 pixels form edges, and other problem is that after editing the sprite with aseprite example adding more tiles, it offsets the sprite in the editor making a tileset\map change so you have to remake everything, and custom physics shape is messed up as well because of more sprites added, I know I can just add png but I really want to change stuff cause if I have layers
