In topics at ruwiki my contribs, are not showing up, if I select the appropriate dropdown menu item of a specific namespace, e.g. namespace 4 (edits from March 26 should be visible there).
Second, slightly different example at hewiki - my contribs, for which the older edits do show up in namespace 5, but not the new ones (from last week) in namespace 3.
It does work properly at mediawiki, afaict.
It seems to work on ptwiki too:
