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.
