Using HD wallets gives you access to a multitude of addresses. Each wallet could simply be generating a qr code for different addresses (both of which you own). Can't say for sure unless you share the qr codes.

QR codes can in fact differ even when they encode the same data, because they may be generated with different levels of error correction. See http://blog.qrstuff.com/2011/12/14/qr-code-error-correction for a pretty readable explanation.

I just set up a personal wallet, and the QR code on my phone, looks different from the QR code that blockchain.info shows. When I scan, the code on blockchain.info, I get the same address. I thought the QR codes were Unique.

what is going on?
This is a new wallet, and I used the copay app, to create it.

Im not sure how to get the QR code off my phone, this is why I went to blockchain.info, so I could get an address I can print. The image from blockchain.info
