I recently discovered that I have a duplicate set of default configurations in my connection preferences.

The default set consists of Wireless Modem, Direct USB/Serial, IR to a PC/Handheld & Standard Modem. This set repeats itself giving me a total of 8 default configurations.

When I try to delete the duplicates a dialog box pops out saying "Default configurations cannot be deleted."

Does anyone know how I can delete the duplicates?
