Wyze Band Sleep Tracking Problem

I have been using my Wyze Band now for about 4 months. The problem I am having tracking my sleep is the band says I get up every morning within a few minutes of 5 AM. This morning I looked at the clock at 1:15 AM & the next time was 6:20 AM but my band said 5:02 AM. Anyone else having a problem or is there a way to correct this.
Thanks, Mike
