That's very weird Geoff. If you ever encounter it again, try instead toggling it on/off by bringing up the song overlay, tapping the second icon at the bottom left and then tapping "Night Mode" to see if that fixes the issue. I'll keep an eye out for the issue though, but I've tested night mode many times and never seen that occur (I usually toggle it on/off through the overlay though).
