Some field labels on plugins are showing up white like the background

Hi there,

I am somewhat new to wordpress, but I’ve been developing websites for some time, so I have at least a general understanding of css and php.

After installing the Woocommerce and Business Directory plugins, and editing them to suit the needs of the site that I’m working on, I realized that the Woocommerce side, all of the labels on the product variation options are white; and on the Business Directory side, the advanced search field labels are white. Since the background of the pages are white, they aren’t showing up at all, and I’m not sure what to edit in order to make them show up. I’m using the Vantage Premium wordpress theme for the website. I’m figuring it’s got to be on the theme settings side, and not the plugins themselves, since it’s happening on more than one plugin.

I figured there would be some sort of small css coding that I could add to the theme’s custom css area, or something along those lines.

Any assistance would be much appreciated.
