3626906 - Aggregate View is not possible in Analytical report with Original Currency measure field

Aggregate View is not possible in Analytical report with Original Currency measure field, with the Amount Accepted (USD or another one from our preference) measure added to the report set, it does allow switching from Detail View to Aggregate View. However, if we remove the Amount Accepted and let just the Original one, it doesn't allow me to change from Detail View to Aggregate View. Why is it occurring?
