Why is there desync in my RemoteEvent?

Edit: I switched over to a Tool and everything is functioning identically to the HopperBin I used, still broken.

Here is a gif of the desync I'm experiencing in a Test Server: https://gyazo.com/4e02b51e729ec2da0bc9895e4688ef69

Here is what is SUPPOSED to happen (tested on Play-Mode not Test Server): https://gyazo.com/bef50cd830af882fe469da25a7855997

Somehow they both see the other person move, but not themselves. Everything else is working fine though. Kinda new to using RemoteEvents and all the FilteringEnabled stuff so I'm really confused, even after reading the wiki.
