The bone spear rings in the battlefields are a known issue.
The 'rags leggings' have a mismatched icon, but at least here when I have the DK unlearn a skill and put the points into Identify Equipment (under Warrior, Craftsmanship), the icon is correct, with the name 'Black Hat of Amazement', which is equipped in the proper slot after giving it to your hero.
BTW both characters have shields equipped (presumably auto-equipped when picking up loot), disabled since they are using 2 handed weapons. You may want to keep an eye on that, since carrying the extra weight can lead to becoming encumbered more easily.
