Thread:Support/Seemingly invalid messages

The following messages appear as not translated to Hebrew in "Extensions used by Wikimedia - Main":
 * MediaWiki:Centralnotice-filters/he
 * MediaWiki:Centralnotice-date/he
 * MediaWiki:Centralnotice-apply-filters/he
 * MediaWiki:Centralnotice-clear-filters/he
 * MediaWiki:Mobile-frontend-disable-images/he
 * MediaWiki:Mwe-upwiz-campaign-conf-idFieldLabelPage/he

All of them appear invalid: When i try to translate them, i only see the documentation from qqq, if it exists, but not the English message and not the suggestions from TM, Microsoft and Google.

What is the problem?
