@tpnotes: Try adding following config to config.lua:
LibrarySort.useOldSort = true
To locate the config.lua, Open Lightroom > Preferences > Presets
Click on "Show Lightroom Presets Folder..."
It should take you to folder ending with ... /Application Support/Adobe/Lightroom/
If config.lua is already present in Lightroom folder, just add,
LibrarySort.useOldSort = true
in the config.lua file. If the file is not present create a file named config.lua and add the same configuration there.
Let me know if it...
