Prosite 3 and 12 Month Payments

I have Pro Sites configured and almost working. When you click either a "Silver" or "Gold" plan all seems good for a single month. However, if I choose 3 month or 12 month on either of these levels it takes me to the Paypal page with the amount populated for a single month. Silver being $5.00 for a single month or $40.00 for 12, selecting 12 month option take me to paypal and shows $5.00 per month. Is there something I can look for in settings for this to work properly?
