Why does Jira Agile have a Sprint column and an Iteration one?

Question

The Agile views appear to use Sprint, and the online help just says that Iteration is a synonym for Sprint. However, when I search issues, I see both a Sprint column, and an Iteration one. If you use Iteration for your query, no records are returned, since that one is blank. Why is it there at all?

That makes sense. I didn't realize you were on Cloud.

I created this JIRA instance on Monday afternoon. I haven't installed the Tempo Planner. I've been using it, and the Product Owner has been entering issues in the backlog, but that's it, so I can't see how anyone added a custom field at this point.

I looked under custom fields, and found that "Iteration" apparently shows up for everyone, just in case they choose to use the Tempo Planner. It's locked, so you can't remove it.
