Trident, Crossbow & Shields appear in model when held in 3rd person.

In several worlds, every time I would find or craft a crossbow, it would appear to be stuck onto my torso, when I craft a shield, it would be lodged inside my head sticking outward in long ways vertical position, and as for the trident... when held, it will appear to be erecting itself out of my neck. They all operate just fine in 1st person and 3rd, but when viewed in 3rd person by myself or with others, it looks pretty funky, and would give an error message such as: "[mojang][error]-minecraft:player.0.9f784920-baa2-4d6c-b5a3-2d4c4c5dcc4f.m2 | binding expression q.item_slot_to_bone_name(c.item_slot) did not return a name?"
