Did you preview and error check the listings before uploading to eBay because preview would show the selected postage services and applied rates.
I would suspect that you have not quite set things up as you intended and regards shipping I only specify a couple of rates and then ask non-UK (as I am UK based) buyers to ask for a quote because as I just said in another thread there are too many options available to list all.
I quickly learned it was best to record all quotes on a spreadsheet against the item so that subsequent enquiries could just be looked up and pasted into a standard reply, it need not take much time when you get organised.
You will find that the more information you put on a listing regarding shipping and terms etc the less it is read.
