Anyone else have issues with scan not stopping on signals?

I was traveling for the holidays and was parked on the interstate for two hours because of a wreck so I was doing a bit of playing with radio.. I had the GD77 scanning FRS (for rx only, just to hear if anyone was talking) and heard nothing for several minutes, then I stopped it scanning and coincidentally stopped on a channel where there was someone talking and their signal was strong and there was a QSO going on, happened to be a GMRS repeater. I started scan again out of curiosity, nothing. Stopped and went to that channel again, same back and forth QSO.
Their signal was quite strong, clear, and I can't think of any reason scan wouldn't have picked it up. Sure scanning will miss periodic transmissions, but I've used a scanner since the 80s and ham radio since the 90s so I am pretty aware of the limitations there. It just seems the GD77 wasn't hearing them at all? The zone I was in had FRS and GMRS in it, so a total of 22 channels, so I'm sure there's no way it just happened to be missing every transmission.
I'm on the Nov 2 2022 firmware, ced2604. I know there have been two updates since this which I hadn't updated to yet, but neither indicate anything related to scanning.
I hadn't looked until today in settings; I found a Scan Dwell setting which, as far as I know is at default at 30mS. I would have tried increasing this time. Is 30mS default?
