Ovulation way off this month on this app

Nicole • Been married to the love of my life for almost 6 years. We have been together for 13 year. Our baby girl is now 11 months old
Was anyone else's ovulation and peak time way off this month according to this app? It was telling me I was ovulating while the app said I was stil AF. MY AF was right but I don't understand how it could say I am ovulating while on my period.
