I play as a left-handed player, and when I retreated from the net to return a lob, the game made my character jump and try to smash the lob, even though the ball was on my right side (in the perfect position for a right-handed smash, but not for a left-handed smash). A related issue is that since the last major update, return of lobs often result in errors when I am just retreating to get into position for a strike (the "normal strike" or whatever happens when I wasn't yet ready to hit the ball).
Here is a picture of the "wrong-handed" smash attempt:
