As of prepatch Demon Hunters no longer have daggers in their weapon skills so they can't collect the appearances anymore, they still show up as collectable in ATT.

This was fixed in the 9c16884 git release and came out with Version 1.6.5 / 1.6.5a . You will need to check class defaults to adjust the setting. We do not push this setting out as forced as it would reset all your settings so it easier to have it done this way.
