As quickly as I got it to only move the cube on the client. The first thing I tried was to jump on my platform. I noticed what was going on. It feels like the server and the client are arguing about what is supposed to be right. The client attempting to win the argument by changing its own position in the world while the server is saying no. I also want to note that even though the server is standing on a stationary box the client is able to watch the server player move as they continue to argue who is right.
Now I am super curious about what other people think when it comes to this how others made it only show on the client.
