ECommerce Shortcode Generator not coming to top

Hi WPMU Gurus,

I'm using the Divi theme by ElegantThemes and I love it, I'm running MarketPress. I want to insert a MarketPress shortcode into a Divi "Text" module. The WYSIWYG editor for editing the text has a button to generate a MarketPress shortcode, however, when you click the button it seems like the dialogue for the shortcode generator remains either offscreen or beneath the Divi Dialogue.

Is there an easy fix to get the shortcode dialogue to appear above the Divi dialogue?

Is this something you can help with?

thank you kindly,
