Maximum number of available bills

There is a scenario where a customer receives one bill containing two consecutive periods. The current development of this scenario makes the drop-down list replicate the statement date since we are showing the bill associated with each period. According to the BRD:

"The bill display will allow the customer to navigate to other billing periods for the same account for up to 36 months"

It's possible to remove the duplicated dates in the list because they represent the same invoice, but it's important to confirm that this is the expected behavior.

In the scenario below, the customer has been billed for 11 periods but only 10 bills were generated because there is one invoice including two billing periods.

We are suggesting other approaches that might give more information to the customer and reduce the confusion of not having consecutive months on the list.
