On my CP Dashboard, I have several collection widgets, for various collections. Only one of them is showing the date on the entries. They all use the same fieldset, and the folder YAML matches, so why don't the others show the date?

example

The folder YAML is this for all of them (except clearly the title is different):

title: News
fieldset: news_article
columns:
  - title
  - slug
  - value: publish_date
    header: "Date"

Am I missing something?
