CVV2 greyed out w/ IE?

Running… [color=#000000]CS-Cart: version [/color]3.0.6 PROFESSIONAL

When I access my site with internet explorer, the cvv2 field with credit card payments is greyed out. In Chrome, Firefox… the site works fine. People can’t skip over the CVV2 either.

Is this a bug with IE that blocks the code from being inserted?

On the tests, I checked out as a guest.
