How to stop billing sales orders after the exact number of billing periods

How to stop billing sales orders after the exact number of billing periods, even if the contract end date is still ongoing?

I created a sales order with a subscription item with a 12-month duration, so the contract start and end dates are exactly one year apart.

But the billing frequency is monthly, and the number of billing periods is 6, so billing should stop after 6 invoices (middle of the year), as expected behavior.

The current behavior is that the invoices are still being generated and have exceeded the number of billing periods.
