Sorry, all I know is that if the correct address is on the listing, the invoices should also have the correct address (it's not unheard of for errors like this to occur, though). I'm not sure where the error would be or how to fix, other than perhaps to suggest not using any of the old templates when next listing.

You could try ending one and rather than re-list, start a new listing from scratch, although I would also contact eBay about it as if it's a technical fault their end, it should't cost you in listing fees (or wasted free listings). Sorry I couldn't be more help.
