Unfortunately, this behavior appears to be how Wyze intended the floodlight to behave w/current firmware versions. I noticed when you are not viewing those cams in realtime from your phone app, their lights stay off and only turn on as programmed in the detection settings. As soon as you scroll down (in vertical view) or swipe to the next page of cams in a group (horizontal view) and the cams go live, their lights are made to trigger for 1 cycle of your light setting, but if you leave the live view up for a few minutes, the lights should turn back off (as long as you dont have them set to always be on).
The problem is scrolling or swiping between cams (if you have several like me) causes the damn floodlight to turn on and off as it comes in and out of realtime viewing.
This upsets me because my side yard looks like daylight with the starlight sensors but the lights ruin that. Also, if I were my neighbors, I might find it slightly annoying.
