Hi again!
Well I don't really understand what you mean, but I'll try to explain how I solved the problem.
I'm assuming you've installed the hebrew language-plugin for CB. This will create following folder:
components/com_comprofiler/plugin/language/hebrew/
Herein you should have a file named hebrew.php, default_language.php etc. In this file you'll have to add following translation-strings:
DEFINE('Group','Your translation');
DEFINE('Groups','Your translation');
This did it for me, hope it'll work for you as well. Good luck and take care.
