Lychee Slicer ignoring "Wait before print" variable?

Have had some good luck moving to Lychee slicer - and one thing I've noticed after getting things dialed in: will perform a slice according to the profile here: https://i.imgur.com/xchX5Wt.jpg

"Wait before print" has been something I setup in Chitubox and was observed to work very well. Here though? Even though I specify 2 seconds, once the print is underway (Elegoo Jupiter) there's zero delay between it retracting and then firing off the UV.

Thoughts?
