Period Log help?!

I am beyond frustrated at this app. My period was a week early, I am generally irregular, so that is not super uncommon. But this will NOT let me edit my period for the month. I selected that it started on 11/14 but it will not let me drag the end Date to today. It will not let me go past 11/15. I am frustrated, have read all kinds of posts and cannot get this figured out. If I don't soon, I'll just delete the app bc it will not be accurate or helpful. :(
