Bizarre sleep report on Macbook Pro?

[Mitramonday]

Please can anyone enlighten me as to these bizarre sleep reports?  My iPhone shows a different sleep total to my iPhone app? It has been synced etc. And then the '0' minutes show detailed graphs? These are the screen shots to explain why I'm confused:

Screen shots from phone:

Screen shots from MacBook:

So, according to my phone, I got 7 hrs 48 mins sleep, until I look at the detail where I got 2 hours 25 mins, plus '0' mins - but shows a 'good' graph?

According to my MacBook it only shows the 2 hrs 25 mins, but with the same 'good' graph for the 0 mins?

To say I'm confused is an understatement🤔 Does anyone have any ideas as to what's gone on? I 'get' that the 2 hr 25 mins graph is 'simplified' but it's the '0' minutes graph that is baffling me?

@Mitramonday It's nice to have you on board!

Let me help you with the discrepancies between your sleep logs on your computer and Fitbit app. Not sure why this is happening but you can try clearing the cache and cookies on your web browser (also try a different browser like Firefox or Chrome) and also log out from the Fitbit app on your phone, restart your phone and log back in.

Let me know how it goes.
