Parts from a player's animation do not replicate to the server

First of all, my animations do indeed replicate to the server but only for the player’s bodyparts. What I struggled with was that my sword didn’t replicate to the server.

I used This topic to weld my sword (the sword is parented to the character).

Then I made my animations using the new roblox’s animator (My character isn’t a custom character) and implement the animations in, however, this glitch occurs:

(The animation is bad because I just quickly made it to demonstrate sorry)
