command block arguments do not work on scoreboard objectives

I have set up a objective called "money" that shows up in the sidebar. I then gave myself some money.

I added 2 command blocks. One that executes "give @p[money_min=1,r=5] 33" and the other "scoreboard players remove @p[money_min=1,r=5] 1"

As expected, activating this configuration exchanges my money for dispensers.

However, the command continues to decrement and spew dispensers until well below zero.
