Clarification of WitchHunter talent update

Feb 16, 2010
The recent update indicated that you made a correction to a display error for the ranking of the Witchhunter talent. Both Witchhunter 1 and Witchhunter 2 are listed as rare talents according to the Central Wiki. Is the Witchhunter2 talent supposed to be Ultra Rare? Is this the reason my Mechanical Owl went from a 470 pedigree prior to the update and is now a 460 pedigree? He had one Ultra Rare talent prior to the update that is now a Rare talent.
