Upgrade Problem and Columns Won't Stay Cleared!

When I clear a column of seen tweets, the column keeps returning. This defeats the whole purpose of clearing the column! Also, when I upgraded to the latest version, it dumped all of my saved groups and customization and I had to start all over again. VERY FRUSTRATING!

ALSO, tweets in each column are all mixed up. They do not show last tweet on top, oldest at the bottom. Just all mixed up. A royal mess to be honest with you. Starting to wonder why I bought this software. Doesn't seem like it's ready for release to me!
