Ci number discrepancies in monthly reporting.

[Passion_of_SNOW]

I am generating a report to show how gradually we have added more and more CIs in PROD through Discovery. However, the numbers are not making sense to me. See below -

I am using the filter below - 

My question is why the CI numbers have changed? Why the same report that I ran on Sept is showing different number of CIs created for each month than the report I am running today in Oct?

Can you go to the data source table and group by created date to confirm the count ?

When using date/time fields for aggregation, try using trend option for reporting. If it does not work, share more details on the reporting configuration.
