Motion Sensitivity issues

I definitely am experiencing issues with motion sensitivity. On my v1 / v2 cameras, at 50 percent setting, clouds passing over the windows (not directly viewed) causing different light levels in the rooms causes triggers on the motion. It isn’t shadows being seen in the room it is tagging the window with the brightness level changes. There should probably be a way that excludes brightness from affecting the motion trigger. But then at 50 percent setting on my pan cams, I am getting no alerts and no recordings what so ever. I think these are different issues but they are all related to the same area.

On the bright side of things, (pun intended), the latest software update has totally corrected all of my issues with the IR filter going in and out, triggering the motion sensor at sunrise, and sunset.
