Problems with the display modes

Question

If I switch one contact list to another, the first list is displayed on the right side of the display (dragging the column headers does not work). Why does it happen?

Answer 1

This is actually a display error. The tabs in the Address Book application can be changed and dragged across the main bar. If you have fields that are displayed off window, scroll to the right and then drag them back. There is also the possibility that one of the fields contains empty space characters. Dragging from right to left should fix this issue.
