Fighting with errors in logs and dupliacte lien in filters fro queries since some weeks,
I finally do a re install test and the bug appears after installing Culture Picker Module.
So

Step to reproduce

1) Install Localization, the culture picker

2)Enable all 3 culture picker feature

3)Create a new Query

4) Add a new filter

5) Scroll to Localization

Here you have 2 lines 'For current culture'....
