Some links at Nav menu in Japanese and other languages are broken

[JinIgarashi]

Some links in other language are shown as None which is pointing to the ****.en.md file.

I found the following two pages have problem of some links in Japanese language.

• Technical reference > Manage conflicts
  • File: conflicts.en.md

https://docs.qfield.org/ja/reference/

Japanse version screenshot.

• Get Started > Tutorial > Qfield > Additional storage
  • File: storage.qfc.en.md

I confirmed this bug presents in other languages like French, Italy too.
I am not sure what can be the reason. Probably nav menu setting in mkdocs yaml for other languages have issues.
