Pick List Won't Populate

I have created a pick List with 5 different options to pick from. I go into Set-up, Customization, Fields and then click on the Module that has my Pick List in it. Since I was changing the names of each of the 5 "picks" I simply clicked "edit" deleted all but one of the "picks" and then added 4 new picks with different names. I then deleted the 5th pick and added that new name and clicked save. Only one of the "picks" is showing in the application. When I go back to edit, all of the changes I made are there, they just don't show up in the actual module. Can someone tell me what I am doing wrong?
