Spawned repeater flickering

I have a repeater that powers a command block with the command "/setblock (repeater's location) 93". When it should spawn an unpowered repeater, it instead goes on an infinite loop, with the repeaters spawning powered for exactly 1 tick. The setup I have involves several of these adjacently positioned, and when the others are powered, they will randomly turn off the other repeaters, and also turn on some randomly as well.
Included is the save.
