difficulty translating one string from english to hebrew

extracted all strings using template extractor
edited with poEdit
translated strings without difficulty, except one string:
"No reviews have been submitted. Maybe you should be the first?"
this string is in the t('XXXXX') format in its source file (nodereview_views.inc)
I see it on poEdit. I am translating it. still can't see translation, instead I see English.
also manuel translation from website doesn't work. I see the string. I am suggesting a translation. translation is saved (i can see it if i edit the string translation again). however, translation is not displayed.
this is the only string that is problematic.
can anyone help with that?
using Nodereview DEV + tallies_2.patch + strings.patch

thanks
