Silly questions
Did you hit the Apply button after adding the columns ?
Are the new columns selected in Preferences->Add your own columns?
Are the new columns hidden - scrolled off to the right ?
If you're using the View Manager plugin, then you'll need to select the new columns in the relevant views.
Could you post a screen shot of Preferences->Add your own columns?
