Command blocks executing w/out required parameters met [duplicate]

I'm trying to use command blocks to spawn a Grinder mob once at a certain spot whenever the player's "Grinders" score is equal to the set ammount. Eg. 1. I'm using this command (With differences for each amount and position):

The setblock sets a block of redstone above a set of command blocks that spawn the Grinder, and those work. However, even when the Grinders score is not met, it places the block, and I can't delete it without first disabling the command block. When inspecting the command block it says it can't execute the command as the player. Please help!
