Airsense 11 sleep time recordings

[hevy6]

I received this on Thursday, and set up the app Thursday night. When I woke up Friday morning is said I slept over 8 hours, then this morning it said I slept over 7 hours, then I took a nap in the afternoon and it said 1.44 hours. The problem is on the app it is saying Friday was on Thursday, Sat was on Friday, and my nap is today. It's not recording the way it's supposed to, and that is a problem because it's on a 2 month rental and if I don't use it 4+ hours a day, it won't pay for it. Why is it recording like this?

A Resmed's day is from noon to noon. The current day doesn't begin until noon and doesn't end until 11:59AM the next day.
