Whenever you hit a player, do this:

continue;

this will tell the loop that you have accomplished what you needed to do in that loop instance(you hit the player, you no longer need to do the rest of the checks for the same player), and to go to the next loop.

Also, there is more that goes into hit detection than the player detection. For instance, you are probably triggering it with a keypress, which could also be the culprit.
