Hreflang problems
Hreflang links tell search engines which language version to show to whom, and an invalid one is ignored.

How Lastmod finds it
The crawl reads the hreflang links and flags invalid codes and versions that do not link back.
What you do
Use valid language codes and make every language version link to all the others, including back to itself.
How the work is followed up
Lastmod looks for your change on the live page and closes the opportunity when the problem is gone. Clicks are followed as context, not as the proof.
