Problem with program indicator

I have a question regarding program indicators.
Why is it not possible to display this program indicator on a monthly basis?

For example, I would like to track the number of students sensitized on the 5 WASH themes.
Here is the configuration I used:

  • Aggregation type: Count
  • Analytic type: Enrollment
  • Limit target: Event date
  • Analytic period boundary type: After the start of the reporting period
  • Expression: Number of records
  • Filter: Different themes

When using the Data Visualizer:

For the entire period of FY25 (July 2024 – June 2025) in the Ambatofinandrahana district, I obtain 20,604 students.

However, when I try to display the indicator by month for FY25, the system shows 2,064 students every month, which is incorrect.
