Check your Adobe account to see what plan it has for your account. You should see an All Apps plan.
If you were paying for Premiere before, and then paid for all apps, nothing will stop the payment for Premiere, so you will be paying for both. You will need to contact Adobe to sort out this mess. Warning, scammers may contact you privately pretending to be Adobe staff. Adobe will never send you a private message asking you to email an account that isn't @adobe.com, or use Skype. Adobe never ask you for their password. These scammers want your Adobe info, credit cards, your money and control of your computer, please take care.
