In the current version I’m playing (0.11.5, obtained via Steam), there are two errors I have seen regarding items.
First, in the Floor Tile type decorations, the Sosig Tile has the incorrect graphic. It instead matches up with the Fleshy Tile / Floor. I did also obtain the Fleshy Tile, that one has its correct graphic, so it’s not a matter of the two being switched.
Second, in the Cards list, there is an issue with the Ent card set. It claims there are only 8 Ent cards, but the abilities granted by the set max out at 9 cards. There do seem to be a total of 9 Ents however, so I’d guess this is just a typo.
