How can I get the shortcodes of an ecommerce platform to function with an accompanying plugin/extension for that same platform?

I am using a specific ecommerce platform called Easy Digital Downloads for a wordpress website which so far works well. However, I want to use its media player but there is a glitch that prevents EDD’s shortcodes from properly displaying through of the entry/text fields of the media player.

Unfortunately, there is only one extension and the author of the extension has refused to address this glitch after wasting months of my time. What is a general way I can get these shortcodes to properly display through the plugin as they are intrinsically meant to?
