Replication Question: Client Boolean Returning True and False. Why?

Thanks in advance for your help!

I have a line trace that detects the distance from the ground. It works great. Using that trace I can do things like automatically extend the landing gear, etc. It works.

The Problem:
When running two players with one as a stand alone server, for some reason, the client returns both true and false to the Boolean. The boolean is “line trace length is less than 300”. In this case the client is over 300.

The same thing happens with the server. Server returns both true and false if the client is under 300 and the server is above 300.

The only way to have all false is if both the server and the client are above 300.
