Paypal payment form wizard causes the Paypal form to disappear

This just started happening today:

Whenever I click the Wizard button to edit my Paypal payment form field, the entire Paypal form instantly disappears, even though the wizard is still "ongoing" and can be "edited" (but after saving and closing the wizard, the form does *not* come back), rendering the entire form broken. 

Please see screenshot after clicking the Wizard.

I checked your form and a clone of your form and was unable to reproduce the issue at this time.  Is this still occurring on your end?  There have been a couple other reports of the happening but it does not seem to be on my end.  Let us know and we will be happy to have another look.

Just tried again and the problem seems to have been fixed for now.
