Item of "x"Follow

You see a lot of items that are "of the bear" "of the wolf" and so on. Also you see "of agility"

Not able to locate these items in Allakhazam database

On my Profiles for example i see my bracer as what it is:
http://wow.allakhazam.com/profile.html?2018

But i click on the item and it shows up with:
http://wow.allakhazam.com/db/item.html?witem=6556

Which takes off the "of the eagle" and the extra stats that are on it.

Any reason for this?

Just another note is that i seen the exact same item name, but the bonus stats differ from just 1 point. Like 1 more agility then the other. But the name is exactly the same. Could that be the reason for not documenting those items?

Thanks. makes sense.
