I'm redesigning our ArcGIS Online account. For one of my groups on the home page everything is fine.

But for the other group, the item summaries don't appear

I checked the setting for the content block and the "Show Summary" button is a descriptor for the block.
Then I went and checked the group and in the list view the descriptions are there.

But in the grid view, they are not.

Did I "flip a switch" I don't remember flipping, or is something rotten in Denmark?
