Link to a page where the issue can be seen: hidden link
I expected to see:
All instances of the Type that the View should show.
Instead, I got:
There is not a single instance of the Post Type to be seen.
It works fine for other Types, so I'm thinking: could this be because I changed the name of the Type in question that fails to show up? The Type is now Gastdocenten, but it used to be Ambassadeurs.
Screenshots show the View while editing the page and a list of two Gastdocenten in the admin view.
I renamed the Type back to the original name and now it works. I need to continue working on other stuff, so I'll leave it at that. Maybe you can test it yourself?
