iTwitter and Tweetdeck issues....... is it just me??

I've googled both of these issues and can't seem to find anyone else with these problems.

First, in iTwitter, I have created separate groups for friends in different locations. No problems there. When I begin following a new user, that person shows up in my list of people I'm following, but they don't show up in the list when I attempt to edit the group. I have figured out that if I delete the app and download it again, it shows all the people I'm following when I want to add them to a group. But, that's a hassle to have to do that every time I begin following a new user. Has anyone else had this problem? How do I get the list to show all the people I'm following so that I can add them to certain groups?

Second, in Tweetdeck, I have about 3 or 4 friends that I follow that do not show up in my Friends list. They show up on Twitter.com, Tweetie, iTwitter, etc., but not on Tweetdeck. Any ideas?

Thanks.

Anybody?

Apparently it's just me
