How do I change delay in purple section for FX intensity

So I’m relatively new to Onyx so forgive me if this is a basic question, but I have a previously created cue that has a varying delay on a number of Rush Par 3 fixtures in the 501-516 range and I can’t figure out how to change the delay in the purple section for FX Intensity? See screenshot. I’m on an NX2 console.

Software Version: 4.2.1052.0
NX Console Type: NX2

This delay was created by using the Wave per X buttons in the FX Timings Section.
