No matter what I add to the translation of the page title. The fuzzy bot keeps on fuzzying the message and emitting the above mentioned error notice. I have no idea how to resolve this and what may be the cause of it. The message conveys no meaning to me. I have several similar use cased on the wiki - working without issues. Here is the page. Any hint is appreciated.

Ok, I figured it out. It is possible to translate the namespace names for namespace category but not for namespace help. I guess a consistent behaviour will be nice.
Could you file a task in Phabricator? This is about MediaWikiMessageChecker::pagenameMessagesCheck incorrectly being applied also to translatable pages.
Sure. Done with task T172382.
