New to Blackberry Pearl 8100 Question?

I`ve had my cell for about 3 month now and am having some trouble with the myfaves. I have 5 of them and two of them work fine (have my sister and one of my friends) but the other three seem to be frozen. I had three other friends there but after deleting them 2 months ago, it still wont let me change the faves spot. It just has the lil faves bubble outlined in yellow and you can see my backround image right thru it. But i cant click on it or anything.
can someone advise me on what to do?
