magento - CSV translation word doesn't work only in a specific server environment -

i configured magento in es_ar , works, translates everithing ok. happends 1 word "wishlist","lista de deseos" works in machine locally, works ok in 1 server in dosnt translate. continues showing "wishlist". , rest of traductions ok. weird. guess? im working magento enterprise versión 1.12.0.0. in advance.

clear cache , refresh - or translate in locale files of magento: app\locale\es_ar\mage_customer.csv

look wishlist there , change it
