Dopdown menu Public - Private - Logged in Users - Friends

Hi all, sorry for the question, I built a Social Network with Buddypress.

When a customer write a post, there’s a dropdown menu with the following options:

Private Friends Logged in Users Public

I’ve edited the mo and po files with Poedit, but I can’t change these strings in italian (I don’t find them).

Would you be so kind to tell me were can I find these strings in BP plugin?

Thank you very much!

Do you use the latest version of your language ?
