Text & Background color same for Select Field when using third-party component

I was following this example [https://codesandbox.io/s/40mr0v2r87](url) on React Final Form - Array Fields. I use third-party component ReactSelectAdapter in the field for my cascading select. The text in the dropdown has a white font just like the background. I looked through the styles but I can't figure out where to change the font color of the select lists.

Is this a bug or is there anywhere in the Style.js file where I can do that?
