Hi,
Thanks, I was ale to reproduce the problem and understand the cause.
Back in 2009 someone contributed a resource file for Hebrew Resource.he.resx, be he only translated a few keys and all the other keys are blank, it would be better if the keys were missing instead of blank because then it would fallback to English for the missing keys, but with the keys there and no values it just renders as empty content. I will remove the blank entries from this file for the next release and hopefully someday someone will send us a more complete translation for Hebrew.
Best,
Joe
