There is a problem where making a long (longer than a orthogonal or diagonal between two adjacent boxes) arrow with a label misplaces the label. The label is placed floating quite far from the arrow if on the outside, close to the arrow if one selects the label on the arrow, and directly between the source and destination cells if on the inside.
To replicate: create an arrow between two far-off cells, make it curve, apply a label, make label either be on left, on right or placed on the arrow.
