Control/Dimming Opti Quad Par and Jands Vista Issues

I recently upgraded my lighting console at my church to a Jands Vista S1, running v2. Since then I have noticed 5 of my Elation Opti Quad Pars (LED- RGBW) flashing white once at random times, this has happened when switching cues, but has also happened when no lights are on in the room. Does anyone have an idea of why this is happening or any possible solutions. I have been trying to figure out if it is a DMX issue, an electrical issue, or an issue with my console.
Thanks!!
