GK JomSocial Stats in front page - translation

Hello, and thanks for the great job.
I'm desperately trying to translate some simple words from the GK JomSocial Stats module in the front page (View all groups - Recent activities - Total members).
I'm going nuts trying to find them anywhere in the database, in some .ini file inside 'language/' folder, or anywhere else in my website tree, but nothing's popping up.
Please, give me some advice
Thanks in advance, and thanks again for the great services you're providing.
