Pro-Sites Page CSS broke and payment coupon issue

First issue I am having:

CSS on registration page is a mess. Even with only “pro-sites” and “domain mapping” plugins and “Twenty Sixteen” theme active (See screenshot). When I activate a WPMU upfront theme, the registration page goes blank.

2nd issue is with Pro-Site coupons:

I generated an absolutely FREE coupon for testing. If no money is due and no recurring payments are due, why does Pro-Sites still send user to PayPal (see screenshot 2) if no money is being charged?
