How to show hidden fields when using Display Suite module to manage display? I'm an addicted user of the fantastic Display Suite module to manage the displays of content types. But it sometime happens that after changing the layout of a content type (e.g. Two stacked column) some field doesn't show up. This happened with the location node field solved in this issue by its author. 

Now, I'm using the Ubercart Auction module which create a content type called 'product'. When you add a product you fill some auction settings. Then when you load the node it shows a form with auction info and links. This one:



So far so good. Now if I go to admin/structure/types/manage/product/display and change the Layout to Two stacked column I get no field to show this form. I get all other fields (body, title, images,...) but no one to show that auction form.

I know that the field is a form but I don't know how make available as field.

How can I solve this?

@lance: 
Maybe I should show where are the auction setting in the node. Look this picture:
You need to enable Extra Fields, which allows Display Suite to manage module-created fields.
