"English" is not appearing in some contexts related to lexemes on Wikidata, as reported in this discussion on d:Wikidata:Project chat. This only occurs in the English localization and in localizations that use English as a fallback in those contexts.
- en: "Unknown language" appears instead of "English" at Special:Search, and "Q1860" appears instead of "English" on lexemes.
- qqx: "wikibaselexeme-unknown-language" appears instead of "English" at Special:Search, and "Q1860" appears instead of "English" on lexemes.
This does not happen for languages that are not English (e.g. "French" for French lexemes), and does not happen when the interface is localized into a different language (e.g. "anglais" with uselang=fr).
The reason for this is not clear.
