Can't sacrifice Cleaned Mallard on the Ancestor Shrine

[reiz01]

Hi,

Same as the title. I simply can't sacrifice the required item on the altar. I have it, It's above required quality, I pick it up and right-click the shrine and nothing happens. I'm using the default client. Attached is the screenshot.

With all the male/female birds they remain different items even after plucked/cleaned, get one of the other sex and it'll work.
