Displaying reward levels using Advanced Crowdfunding

I wish to use the Fundraising Plugin for advanced crowdfunding on a new product. I cannot seem to figure out how to get the various pledge amounts to appear on the page. This is the main concern.
I have Paypal sandbox APIs and emails all set up. When doing a transaction on sandbox.paypal.com, all seems in order. I watched the fundraising plugin video and thought I matched all the steps, but no rewards display...not sure what I am missing.
A second concern is that if I add a donate button, it wants to direct me to real Paypal instead of sandbox Paypal.
Any help you could offer in these matters - particularly the crowdfunding matter - would be so appreciated. Also, I have enabled access to the site for WPMUDEV.
