Help Adding to Contact Groups

[nephronman]

When I initially bought by Droid X, I was able to enter new Contacts in my Contact Groups (i.e. Restaurants, Pharmacies, etc.) These original groups remain but after an (uninvited) upgrade to my Android System (currently 4.5.621.MB810.Verizon.en.US; Android version 2.3.4), I can no longer add new contacts to any of my groups.

I can add new contacts but they are displayed alphabetically (by "First Name") in a large general Contacts listing.

Suggestions?
