How do I remove a single element from a data structure in the editor?

There’s a button to add an element, and one to delete all. So how do I delete a single element?

(sorry if this is a dup, I hit “ask a question” and saw no evidence that it had been posted)

I think you are doing a right click in your picture? Try clicking on the small arrow on the right side, it should give you the option to delete a single element.
