Realms Experimental Gameplay

So, I uploaded an experimental gameplay world onto realms, but the experimental gameplay features aren't seeming to work.  I downloaded it again to make sure that experimental gameplay was on, and it is.  I also exported the world to the standalone server and it doesn't seem to be working there either.  The only way it seems to work is if I host a game via multiplayer from my game client, which seems odd my game client would gave a server feature that the realm I paid for and the standalone do not.  What am I doing wrong here?
