With the new listing system, if I try to override postage costs for a particular listing, it won't let me list the item and displays an error message:

"If overrides are provided for domestic postage, you need to provide overrides for all services in domestic postage."

Overrides worked with the previous system, but the new system (which I have been forced to used now) will not allow postage overrides.

Am I missing something or is it just eBay failing? I've tried asking eBay through the chat system and the dude just said they'd let someone else know the error was happening (useless).
