Selected Donation/Reward Level amounts not transferring to Paypal


I am setting up a fundraising project using simple donations with several donation/reward levels.

While testing the project (via the .wdf_fundraiser_panel), I noticed that if you make a selection from the various .wdf_reward radio buttons, that the amount selected does not get transferred to Paypal when the .wdf_send_donation button is pressed. The only amounts that get transferred are the ones entered in the .wdf_pledge_amount input box.

Is this as designed or am I doing something wrong/missing something?

Any assistance would be greatly appreciated.
