UO Second Age

I just created several potion kegs with my tinker/carpenter. When I added orange potions purchased from the provisioner to the keg the name changed to "Recovered from a shipwreck" and "the keg is aproximately half full". Shouldn't the name change to "a keg containing orange potions". Obviously, since I created the keg components from ingots and logs I mined and chopped from trees no part of it came from a ship wreck???

I've filled two of the kegs with orange potions and received the same result.
