Bugs (?) with Normal Loot Filter

Some items, most specifically backgrounds, are not displayed separately when the loot filter is set to Normal.

Other items that may or may not be intended to be shown:
All items obtained in your castle, including Goblet, Dwarves, Prophecies, etc. show up in a regular loot window on Normal.

Gambling tickets from the Riddle Dwarf show up on the side on Normal.
