Fenix 8 Strobe After Sunset Bug

I have the Fenix 8 47mm AMOLED, and in my activity settings for running, I have it set where after sunset the Strobe light should activate. The issue I experienced is that the "After Sunset" part does not factor in. It just always turns on when the activity is started regardless of the time. A few nights ago I went for a round at 6:15pm and the strobe turned on when I started the activity (Sunset wasn't until 6:46pm that day, according to my watch). Then yesterday I went for a run at 7am, and the strobe turned on when I started the activity even though the sun had risen (sunrise was 6:34am) already.

Has anyone else experienced this? Or am I misunderstanding the settings?
