Hi DRG,
I think for this we will need more information, and unfortunately that will most likely involve your email and other personal information. I would recommend reaching out to Canvas support, or to Badgr support, and seeing if they are able to help assist more on this matter.
Before reaching out to the support teams, ensuring that the account you earned the badge on, and the backpack's account both have the same email address would help as a starting point for an issue like this.
