Sitemap Weirdness in Multilingual website

Is that normal for a multilingual website. I’ve seen a lot fo sitemaps and never seen one like that. Whenever I go to:
/en/sitemap.xml or /fr/sitemap.xml don’t look like sitemaps at all.
Thoughts?

yes this is correct, you should have a sitemap per language.

Yes, true, but then

/en/sitemap.xml doesn’t look like a sitemap.

If you use any Sitemap XML validator out there, including submitting the sitemap to Google Search Console, you will see that the generated sitemaps by Hugo are 100% valid.
