Does the app ignore +OPK?

Stephanie

I know I ovulated on 1/6 and logged it. My fertile days were supposed to be 1/2-1/8z

AF was supposed to arrive 1/20.

She didn’t arrive until 1/28. When I logged my period the app it hanged my fertile window to 1/9-1/15. Does the app ignore my positive OPK and automatically change my dates? The original fertile window was accurate.
