I removed Twitter, but FriendFeed still shows new tweets

I've removed Twitter from the services I have pumped into FriendFeed, but my tweets still appear on my FriendFeed page (http://friendfeed.com/mjkeliher). It's been about 24 hours since I removed Twitter from my list of FriendFeed services. Why is this still happening?

It's a problem because I'd like to take my RSS feed from FriendFeed and pump it into Twitter via TwitterFeed. But if FF is still importing my tweets, this creates a nasty, unending loop of Twitter messages.
