Prorate and change renew date

[Blesta Addons]

today a client want to renew his service before the expiration date and the invoice was generated, so i have go to edit service, change renew date and changed the expiration date to +1year (from 26/092018 to 26/09/2019) and checked Prorate . but there is no invoice was generated ! is this a normal behavior or i have misunderstand the prorate in this section ?

That's not normal. The renew date change to add a new year should be prorated, and an invoice should be created for the difference. I've created CORE-2769 to look into it.
