Glow changing my ovulation date?

Al

So I started my period today at 9 DPO and every time I enter today as day one of my period, it moves my ovulation date backward to two weeks before AF. Which is NOT when I ovulated.

I like to keep my tracking accurate and this wasn’t a problem before until recently.. not all of us have a 14 day luteal phase so I’m not sure why glow is making that standard.

Any help?
