Data Discrepancy in Looker Studio

[Chloee]

Why there is difference between the active user sum for each campaign and the grand total of active users ? I created a custom table in Looker Studio. Grand Total = Show Summary Row

Thank you for your query!

The Show summary row option toggles the display of a row at the bottom of a table that summarizes each metric column. Please verify how you have sorted the field of interest/ filtered it in order to see fi that has caused redundancies that is causing the discrepancy between the '9' that it should be vs. '15' total it shows.
