You correctly moved most of the existing footprints to align them.--- Some features I've flagged are footprints where you first deleted an existing footprint before adding a new one in their place. It can be more difficult to edit the existing data but it helps to preserve the meta data of the features. Delete features when you think that those features are invalid and do not represent features which are there in reality; not to delete and redraw them.--- There are a few places where you inaccurately glued nodes: hold alt to prevent your cursor from snapping to existing nodes.
