Do you want the sprites with the pivot values that I use? Import only the animations I think don't make sense because I did following specifics patterns for my game

This can be caused because of the pivot on the sprite, but also if you are using the collider/character body in the same object as the sprite renderer, if you use then separated I think you can avoid this shift problem. But on the game I used the VFX and the movements sprites separated, I think it's easier
