It it possible to change quiz features (radio buttons, fill in the blank drop downs, etc.)?

Hey All,

New Captivate user here. (I'm running Captivate 2019, v. 11.5.5.678) I have added in quiz questions and when previewing the question slides, I cannot see the difference before and after selecting an answer.  I have changed my theme colors hoping that was the issue but nothing changed.  

This is before clicking anywhere on the question screen:

This is while clicking on the blank to see a drop down:

And this is after select an answer (any answer correct or incorrect):

I an also seeing the same issue with radio buttons when I select true/false and multiple choice answers.
