Hi there-
I believe I just answered the email you sent to Support, but I wanted to post the main points below in case anyone else has this question. :)
The container card you are referring to is called the the Sections List in OmniOutliner, and it acts as an overview of the highest-level items in your outline, which means the information in Level 1 rows of Column 1 and their child rows. Click a section title to temporarily hoist that section to the top level, so you can concentrate on that section and ignore the rest of the outline.

This means that if you want to see text associated with your level 1 rows, you would need to create a level 1 row, then add any text or information you want included in that Section as Child rows. Then, when you click on any of the Sections in the Sections list, you will see the Level 1 row as the title of the Section, and the Child Row text displayed below.

I've attached two "test" screenshots: View 1 is a simple Level 1 Row and Child Setup, and View 2 is the Hoisted view of the first Level 1 row and its Child row. I hope this helps!
