In the first image I received a drop of Serpent Shield-J+Skill and it wouldn't let me loot which my guess was because of the weird -J+Skill affix. This only happened once, so I'm not sure you can do anything except check the drop table and make sure it isn't a typo in the item drop. The second image, I have had several drops like this when hunting the mini-bosses, a Lucky set item is dropping and I get the "You cannot get the item" text, whether I am in a party or not or if the item is for my class or not. Are the lucky items supposed to be dropping? If so, why can't we loot them? If we can't loot them, would it be possible that they be removed from the drop tables of the mini-boss mobs?
