All right, I just got off the phone with Apple, I had a different question but while I had them on the phone I asked again about this issue and where to find the prefs file and we found it and I changed the 0 to 1 and now my library elements are all in alphabetical order again . . .

Finder > hold down the option key and click on GO in menu and scroll down to Library and then Application Support. Click on Poser Pro > 11 > LIB_ITEMS_SERVER_SORT 1

You will change the 0 to 1
