Stripe Credit or Debit Requirement

Hello, 
I received an email from a client we set up a long time ago with Joomdonation using Stripe. There is now a field appearing in the Card checkout section, requiring the user indicate if their card is a credit or debit card, but there is no field option for them to choose from. I'm attaching a screenshot for reference.

I don't recall this being there previously and am a bit stymied as to where it might have been added from, so I can turn it off. It doesn't seem to be an option in the Stripe Payment Plugin, but maybe I'm missing something.

Any ideas?

Thanks,
Mal

Oh geez. Nevermind. They'd tried to update the plugin on their own. Please disregard.

OK Malice. Thanks for the info.
