Currently all core entities have own implementation for language element value.

(Drupal 8 Multilingual Initiative) is the tag used by the multilingual initiative to mark core issues (and some contributed module issues). For versions other than Drupal 8, use the i18n (Internationalization) tag on issues which involve or affect multilingual / multinational support. That is preferred over Translation.
Not all content is available!
It's likely this issue predates Contrib.social: some issue and comment data are missing.
This was fixed for MenuFormController in #2301317: MenuLinkNG part4: Conversion → and a usage for Taxonomy in #2355909: language.settings config is not scalable → and the last usage was block that was fixed in #2355909: language.settings config is not scalable → .
Therefor, closing as outdated.
