When you start Kleopatra, the certificate filter is set to "All" or the equivalent in other languages, e.g. "Alle" in German.
So in German, the tabs will start out with "Alle" but on the first or second filter change switch to "Abgelaufen", which is the first entry in the filter list.
Here the filter dropdown shows "Abgelaufen" from the start but the tabs show "Alle" (this was after only a language change only and not fresh install):
It seems the first filter change works sometimes:
The second then shows "expired", regardless of what was chosen:
The behavior shows in VS-Desktop-3.4.0-beta1294 and AppImage-3.4.0-beta1311.
The filter still worked in vsd-beta1250
