[Cerrado] hreflang not appearing

Background of the issue:
I am trying to understand why the hreflang tag is not appearing on pages where the translation is finished. Additionally, I am facing an issue with translating the homepage, which is stuck at 50% completion for an hour.

Symptoms:
The hreflang tag is not appearing on translated pages. The homepage translation progress is stuck at 50%, showing 'less than 1 minute' for an hour.

Questions:
Why isn't the hreflang tag appearing on pages where the translation is finished?
Why is the homepage translation stuck at 50% completion?
