How to Display Nickname 2 in Slip List

SOLVED

I am trying to figure out how to show the Nickname 2 field in the Slip List. I recently switched computers at work, and on one computer, for the Client field in the Slip List, it displays the Nickname 2, eg Bob-Smith. But on this other computer, it displays the Nickname 1, eg Bob.00000. I desperately want to show the Nickname 2 for the Client field in the Slip List, but I cannot figure out how to. I have combed through the preferences on the old computer to try to put in the exact settings on the new computer, but I cannot find the discrepancy. 

I have Common selected for the Field Theme, and the Client field shows the Nickname 1 on the new computer, but shows the Nickname 2 on the old computer. How do I rectify this?
