Select a dowloadable product

I have just dowloaded the plugin and need some direction. I have created a “page” which appears under “all downloads” = ETD downloads. I have uploaded a document to that page.

When I attempt to add that shortcode to the POST – it is grayed out now allowing me to make a selection

When I attemtp to add that shortdoce to a PAGE – it allows for me to make the selections and the document that was downloaded. but when i click to “Insert short code”, i receive an error to choose a downloadable product
