Access Point keeps registering to the wrong WLC, ignoring the WLC I specified in option 43. I confirmed the HEX value is correctly entered on the DHCP server using multiple generators. Any suggestions?

Yes. However, factory reset without the temporarily removing DNS entry didn't resolve the issue for some reason.
