Thread:Project:Current issues/Filter translations in recent changes doesn't work/reply (6)

The hidden translations are in the [ Translations: namespace] and there are effectively hidden in your view (“Filter out translations”). When someone translates something, her/his edits are duplicated in the Translations: namespace and in the actual translated page (in the main namespace or elsewhere).

If you want not to see the multiple lines, you should use the tip given by Nemo. Alternatively you can register for an account (top right of the screen) where you can set this behaviour as your default preference.
