You probably put the Insert buttons from the Edit category on the
toolbar rather than those from the Insert category (if you're using All
Commands, use the Column command rather than the Insert Column command)
The Edit category buttons apply to the List Manager. Unfortunately, the
icons are identical with the Insert category buttons. It has been
suggested before that MacBU change the icons. Probably worth suggesting
again via Help/Feedback...
