Renew Listing Says "Renew for 30 Days" but Renews for Longer

I have 2 listings set up. 1 for free that’s 6 months and 1 for a year that’s paid for. I was doing tests to figure out the renew system and when an ad expires and I go to click “Renew ad” it says “Renew for 30 days” However, when I click renew it renews it for the amount of time I have set (6 months for free and 1 year for paid) Is there a way to get the Renew Listing to say the amount of time it will actually renew for? Very confusing for a user
