Something strange since the latest update...

I have a custom page for the memberships:

http://www.domin8.ca/contest-prep-personal-training-packages/..

Now, you used to be able to click on the "Sign Up" Buttons (IE:http://www.domin8.ca/register/?membership_id=7163) and it would automatically take you too the corresponding paypal page for payment... but now it just takes you too the below URL which is the membships listed again, but just the plugins version: http://www.domin8.ca/memberships??? So now the customer basically has to select the pricing options twice..??

How do you fix this?
