I have the same thing from time to time in the 1/2 bath of our 2020. The video posted earlier shows the answer. You’ll notice on the discharge from the macerator which goes up there’s a check valve before the line turns 180 degrees and heads down. If that check valve doesn’t seal completely a small amount of black water from the discharge will leak back into the bowl. Usually a second flush when this happens takes care of the problem so I haven’t bothered messing with it.
