Pro Sites, Stripe and yearly subscription period don't work


I have set for my site 2 levels with only 12 months period activated, but to stripe are sent all 3 periods: 1 month with 0 price , 3 months with 0 price, 12 months with price set by me.

When the user pay for 12 months subscription he actually gets 1 month with 0 payment.
You can see it on my site, I also granted the access.

Best regards,
