Translate Filter Product


i have to translate "Price" and "Brand" product filter, i've edit filter (Product > FIlter) and changed with right value but the site don't change the value, i've tryed to change langue from backend too... the value change ONLY if i change the admin panel language... what's wrong?

Thanks in advance

Note that there are 2 boxes with languages in the admin panel:

Make sure that the correct language is selected in both boxes

Right... now it work fine... i think it was a cache problem
