GiveWP Paypal donations or pay with card keeps disappearing

Not sure if anyone noticed this issue, but it took me a while to figure out the issue and replicate it. I was not able to find on internet the solution.

the issue: when connecting GiveWP with paypal and using Credit Card option, it also gives the option for paypal secure payment but when clicking on paypal the popup screen disappears in couple of seconds without indication of any issue. what I realized is because the required fields that I set in the plugin are not filled, but unlike PayPal standard when it shows you in red that Name field is required by highlining it, in credit card option this does not happen and you keep trying to understand what is the issue and something is not working.

hope GiveWP will address this issues ASAP.
