How to get rid of FaceBook Notifications on a Droid Eris?

I just recently bought a HTC Droid Eris, and really like the phone. But a problem that I have with it is, when I click on People, and then Updates, it shows that I have 700+ updates and when clicking on it, it’s all the updates that I’ve seen already.

I tried clearing them all on my computer but have found no change on the phone, also tried logging out and restarting the phone. No luck. I’m really anal about my phone and want it to be working in tip top condition but it’s hard to know if I have a facebook update or not because the counter will only go up! Please help me!!!
