Recent files (exposè) stopped working in iWork suite

Hello,

In Keynote, Pages and Numbers I can access my recent files from "File - Open recent", but no longer by swiping down with three fingers or by clicking the icon of the app and holding the click. These two routes will display instead an old list of recent files, say from one month ago.

Since the latter two were my favourite ways of opening recent files, any advices?

Thanks!
