Sure.

So basically we have two ways to extract sprites from sprite sheets.

1) automatically :  unreal will try to find the best bounding box for each sprite then extract them, but this often lead to issues where separated pixels or not aligned pixels are treated as a whole image to export 

( Screenshots, 1 yellow square = one image detected to extract)

2) the other way is to manually set grids heights/length with margins.
but this works well only if the sprite sheet is clipping all the images in a good way ( thus putting every sprites in a x,y distance where x,y are the biggest "bounding box" of the biggest sprite in the sheet

The easiest fix is to provide One sprite sheet with big bouding boxes (like 124x124 or more to accommodate the biggest sprite)
OR
Just Put single images for complex sprites.





(so here I cropped barriers into single images so i can import the whole sprite)
