Membership plugin - removing default text

I would like to remove the default text from the subscription sign up page at http://www.racingtoregister.com/team-registration/
The plugin is being used to sign up team members.
I'd like to remove "Select a Subscription

We have the following subscriptions available for our site. To join, simply click on the Sign Up button and then complete the registration details."
as it isn't relevant for those signing up to be on the team.
