How can I display Prosites "display an option on register page"?

The "Display an option on sign up page" option is not displaying properly on my register-store page.

The radio buttons show but not any of the text. It appears that the container is not high enough for all the content to show.

What is the best way to fix this issue? I could not locate the css file or php script that adjusts the height of the element, assuming this is the issue.

I have a screenshot. Where can I send it to?

Thank you.
