Pro Sites - PayPal payment received but site not extended

I've had so many problems with Pro Sites and PayPal. The site had a successful payment on 10/11 but still, the site was expired!! This is happening every month on this site. I've just manually added a month to her site but this problem needs to be fixed! When I look at the PayPal account page it shows the active subscription and correct payment history but when I look at the Pro Sites account page - it shows the payment history but does not extend the site.
