Reboot again and your good to go with the new bios, backup bios can not be changed yet i believe like on Gig boards but that might change.
You sure about the shutdown and move the jumper back to 12?

What I did
- move the jumper to backup bios 23
- boot the system
- asrock logo showup then it redirects to a screen asking for the bios file
- if I shoutdown and move back the jumper to 12, it doesn't ask me to flash and it boots with the old bios
