New Course Players Features

I’m working on making some UI changes to our eLearning, which includes turning off the lightbox nav (Previous and Next buttons) when an eLearning is launched. I like the way it looks in the current course player, however when I turn on the new course player preview, my lightbox setting is set to hide, but it’s still showing when I launch a course. Is this the design (which doesn’t make sense), a bug, or the functionality just isn’t fully worked out in the preview?
