Problem Setting up Server Properties

[DeadlyPeanut]

My server just seems to be completely ignoring my properties. I like to play on easy with no mob hostile mob spawns... Why idk just the way i like it have to maintain a source of food and get to be left alone. On my vanilla server this works fine with these
