Registration Page – step 2 subscription – description not showing up – random black box


After switching my site to a new theme ('Professional' by Elegant Themes) I ran into a Registration Page problem at step 2 – see screenshot. What can be done about this to get it fixed?

***My settings are below, and worked fine in the past:

1. I have registration disabled in your sites options.

2. I have created a "Registration" page with the subscription shortcode on it and assigned this as my registration page in the membership options.
