Some twitter contact information not showing up

[Stephen D Smith]

I'm a new user to WP8, just coming over from iOS to a shiny new Lumia 920. So far I love the device and the OS, but I'm having a bit of a weird problem. I've connected to my twitter and facebook accounts, and Twitter account information for certain contacts is not showing up. Not all of them, just one or two. I tried disconnecting from twitter and reconnecting through the email + section, but that didn't fix anything. For instance, @friend1 has an account on twitter. We talk regularly through the service, as he doesn't use his FB account very often. His FB info is in contacts, but not his Twitter info, and I can't edit/add it. However, @friend2 has both Fb and Twitter accounts, and his information is in my contacts and his posts show up in the group I have them assigned to.
