Why do sleep graphs look broken?

Currently on Google Pixel 2 and have a Fitbit versa lite. 

The first two days the sleep logged like it does in the articles, so I assume it's correct and also gave me a sleep score.

However for the next two days my sleep graphs just look like bar charts and are not giving me a sleep score. I updated and restarted my Fitbit as well as logged out and in of my account but the graphs still look broken. Is this normal?

Thanks!

When I click on the days, there's a definite disparity between the screens as well.

@Rich_Laueyes it is,

I found the section in this help article that would explain why my graphs look weird. Apparently I might be wearing my Fitbit too loosely and shouldn't be using the 'begin sleep now' button and instead let my Fitbit auto detect sleep. Will try again tonight but this is a bit frustrating

Thank you for telling me about the image icon, I didn't see it previously.
