Continuous Modulator Only Playing One Sound Pitch

I have a level cue with a single audio file attached to a continuous modulator, but when I set the input/output values, it only plays the sound at one pitch instead of randomizing it every single time. Is there something else I am supposed to do to make the pitch randomizer work continuously?

You need to set the parameters yourself via blueprints.
