Difference between numbers in Google Sheet and Looker

[mvdries]

Hi community - i'm having issues with showing correct numbers in Google Looker with data from Google Sheet. 

In Google Sheet I have events as high as, for example, 5058 but in Google Looker, the highest event count I get is 9. 

- The date range is the same 
- the count of the metrics are in [sum] 

what is going wrong here? I'm getting desperate... thank you!
