Is that a bug or glitch? I played a ton of NHL 19 and never had this issue, but if you are only 9 games in and it's an annoyance, I would restart. Use the preseason to see if the bug is fixed by playing on an easy mode and aim for a OT scenario.
The only place I've seen points like that is in the international tournaments where there is different points for OTW and OTL.
