The only way around this that I have found is to place a line segment about half as long as the leader line (of the same pen, with no shadow) on top of the leader line that is being masked by the shadow of the other leader lines. Pop all of your shadowed leader lines above the lineart, and the short segment(s) above the shadowed leader lines.
