I create a table in looker studio with the parameters: date, country, device category, views, sessions and total users, the summatory in looker studio specifically in sessions and total users are wrong, I verify this exporting the data and doing the summatory manually in excel. It also happens in the report of GA4, so there is a solution to this issue?

enter image description here

I did the summatory of the columns using excel but the results doesn’t match, also tried another methods to export the data like format, downloading the reports in GA4, looker studio, even google sheets using an extension
