[Visual Bug?] Movement on drawn Veldian Knives on "Try On" but not in actual game

Heyho,

just got the Veldian Knives from the new Monster Hunter Crossover via weapon coffer. Before opening I used "Try On" on all weapons at the vendor, to see which one I liked most, and the flexible motion of this knife/whip combo for the ninja weapon made it a very easy decision. Sadly, when I equipped them, they were as stiff as any knife. So either the movement in the "Try On" is a bug or the lack of movement in the actual weapon is unintended. Either way, please make them consistent so people know what they're actually buying beforehand. Ideally change the actual weapon motion, I'd love to have them swoosh around like this! :o (And when the physics animation clearly already exists, one might as well use it.)

Date & Time: 07 October 2025, observed around 18:45 UTC+2
Frequency: seems permanent
World name: Twintania
Character name: Minali Flo'uf
NPC name: Smithy in Tuliyollal is selling them, but that aside no NPC seems to be involved in creating the bug
Class/Level: Ninja/100
Party or solo: solo
In-game time: irrelevant because permanent
Area and coordinates: Tested at the striking dummies in Wachunpelo, Urqopacha, Yok Tural and in Tuliyollal next to the vendor (13.2;13.3)

Steps:
1. Get the Veldian Knives from the vendor or the weapon coffer.
2. Use the "Try On" feature with the weapons drawn preview on
3. Move the preview character around and observe the awesome wobbly motions of the knife/whip combo weapon
4. Equip the weapon
5. Draw it for real in the game with your actual character
6. Move around, maybe hit a striking dummy, observe how they are solid.

(Highly doubt connection specs or PC specs are going to matter, so I'm leaving them out.)
