Unable to submit iOS app for review - “There are one or more errors on the page.”

Question

I wanted to submit my app for the App Store on iTunes Connect, but whatever I do I got this last message telling me there are still one or more errors on the page.

Answer 1

For me there was an extra language listed. However, in the drop-down list it was blank and there was no error indicating a problem. So it was hard to catch. Check out the screenshot. Once I deleted it is said the language was "Flemish" which I never even heard of.
