I've installed WPForms plugin for all my contact forms. There seems to be a conflict with the dropdown fields of my forms - it does not show the arrow that identifies multiple options. I have tested by switching to a different theme, and they show up. When I come back to Cesis, they disappear again. 

I've also tested by removing all my custom CSS. No luck.

I have reached out to WPForms, and they suggest I contact the Theme builder.

Can you please direct me where to go to revert this?

Many thanks

Finally found it. Not sure why it's defaulted to be off... 

div.wpforms-container-full .wpforms-form select {
    -moz-appearance: menulist !important;
    -webkit-appearance: menulist !important;
}
