Printing label, eBay label appeared as Parcel - I did not offer that!

[kitchen-topia]

Well, this was interesting but not much fun. 

Can anyone tell me how this happened and what to do (next time)? 
I sold a pair of jeans, I offered;
1) padded flat rate priority envelope
2) express flat rate envelope 
that's all. 

The label came up and I printed it not noticing the system had selected Parcel Select Ground ($11.00+!!!!!). 
I know how to void a label, I did that and printed a new one at PFRP, that's done. 
But WHY would the eBay system select Parcel when I did not offer it? 
I know, I know, gotta look at the page before I print it.

The new Shipping label form-- sorry, I mean "experience"-- throws all kinds of odd and irrelevant shipping options at you when you first open the form. The default (selected) choice is supposed to be your default method offered in your listing, or whichever one the buyer selected (and paid for, if not Free Shipping), but I could see how a wandering mouse could inadvertently pick one of the other methods while you're trying to scroll down that wasteful expanse of page that they've put into the redesign.

Try going back into the Shipping form again as if you were going to print another label, and see which Shipping choice is selected when you first get in there. Then see if any mouse clicks, drags, thumbwheel rolling or Tab commands might change the selected radio button from your intended method to Parcel instead.

If the dimensions you had in the shipping section of the listing do not fit in a particular USPS packaging option, that option will not be shown. (applies to Flat rate envelopes and boxes and Regional Rate boxes)

If any dimension is larger than one of 12" L or 9" W or 3" D the USPS Priority Mail Flat Rate Envelope will not be displayed

(you have to switch to the USPS Packaging tab to see the PFRE option then)
