Glitch in the app

Marie-claire
Hi is anyone else with a period from 17-21st sept experiencing a problem? I have my period logged correctly in my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> but for some reason when I click done and go back to the normal calendar glow has my period Dow. As being from20-24th sept meaning my green fertile days are all about 4 days out. My home page still has the correct day for my next due period and my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period calendar</a> has it right but the main day to day calendar doesn't seem to have calibrated with the info I've given. It worked fine when I was in my period it's just suddenly changed two days ago an moved all my period info logs to the wrong days too. Has anyone else got this problem?
