The total value of the table changing when downloading or delivering a report

[Masa1]

I’m using GA4 as the data source.
I’m using a pivot table as row dimension=city and column dimension=date.
The total value displayed on Looker Studio changes to a different value when downloading or using the scheduled delivery of a report.

(Below is the grand total displayed in Looker Studio)

(Below is the grand total displayed on the generated PDF report)

It would be greatly appreciated if you could tell us the cause and solution as to why the grand total value is changed wrongly at the time of download or scheduled delivery.

Thanks,
Masa
