please help me!

how do I log that my period started today? I've been using glow for years and since the update I'm having issues. my period is a day late and it asks if my period came today. when I tap on the yes answer it takes me to my calender. when I click on today, it lets me choose The flow of my period but it won't mark that my period started. I'm not sure what I'm doing wrong.. help please!
