Ribbit: Edit Friends Issue. (The list update but not as the user want)

Hi there. I am making the Ribbit App. I can log in /out and sign up users. I have my list of friends as well. But I have an issue when I try to select my friends. Looks like there is certain in the execute command because when I try to change my friends is not really update as i want.
