Aggregation issue in Event reports

I have a tracker program capturing numbers of supply and demand of oxygen cylinders. The data elements are of number type and sum for aggregation. The event reports however are displayed counting. For example; No. of cylinders ordered over 3 days could be 2,4,2. Ideally, you’d expect a sum of 8 to be returned but the event report will instead display 2 of 2 and 1 of 4.

Hey @herbert_kiwalya,
Would you share the program rule used as well as screenshot maybe? Also, what is the version of the DHIS2 instance you are using? Thank you! (:
