Visual Editor Not functioning well in Muffin Builder

I'm building a page and have the Visual Editor Item from Muffin builder loaded. When you click to edit, the right side of the edit screen is out of the box. You can't get to the scroll, nor can you move the cursor down. It seems stuck.

When using the html view, you can see the entire box.

If you contact me I'll be happy to provide you with login info for you to see. Running latest version of WP and BeTheme 11.9.
