Contact form 7 dropdown navigation not showing required validation highlight

I am having issues getting my contact form 7 to highlight the required dropdown’s when the form shows the error. All fields are highlighting correctly except the dropdown’s. Please help.

The issue is from my contact form on http://www.twinfoldcapital.com/apply-now/ and http://www.twinfoldcapital.com/apply-now/

Thank you!
