Kinetic Augment not working properly on horse

[Cubicllama]

I am attempting to make self-driving horses. The walk() function seems not to work: it returns true as if it were successful, but the horse ignores the command and either doesn't move or just wanders around aimlessly like normal. I have tried using the disableAI() function, but that also doesn't seem to do anything. Other kinetic augment functions such as launch() work fine.

(MC1.12.2, with plethora version 1.12.1)
