Page language disagrees with its hreflang

Warning severity, in the Hreflang tab

Why it matters

The html lang attribute and the page's own hreflang entry name different languages, a sign of copied templates or wrong annotations.

How to fix it

Make the lang attribute and the self-referencing hreflang agree on the primary language.
