An issue in the billing process logic where multiple changes made within the same period were causing the prorated amount to be incorrect has been fixed. This was specifically reported when the Service Code Proration method is set to Calendar Days - Start and End. Now, after billing calculations, the prorated amounts are showing correctly.

In this example, the invoice displayed shows a total of $129.06, which is equal to the calculated prorated costs based on the 4 changes made throughout the period.
