Some carriers only record weight internally and wont show it on the tracking page, so you should be fine.

If you want to be extra safe simply use Adobe Acrobat and edit the 10.00 to 0.1

After the return gets delivered contact paypal and provide them the tracking number and a picture of the shipping label. If you do decide to edit the 10.00 to 0.1 as mentioned above, make sure you show paypal the original 10.00 label.

But in all honestly you don't need to edit the label as people make mistakes when creating a pre paid label all the time. Just because it has 10.00 on it it doesn't mean it has to weigh that.
