Cycle Chart

My chart is all sorts of messed up. AF came earlier than predicted by my previous app (on the 24th instead of the 28th). Now that I've logged it and it's over, my Glow chart won't reset and show me when I'll ovulate. It's got me having another period in two weeks and that today is my most fertile day!? I don't know how to fix it so that it predicts accurately when my period will be and when I'm fertile, help!
