The values under the three Custom difficulty headings count only when Difficulty preset is Custom: use the settings below. Set that, then click Save & restart.
Fix it
- Open your server in the panel and click the Settings tab.
- Under Config files, click Gameplay Settings.
- Under Difficulty, set Difficulty preset to Custom: use the settings below.

- Check your values under Custom difficulty: players, world and enemies.
- Click Save & restart. With Save only, the change waits for the next restart.
Any other preset, such as Hard, makes the game ignore the custom values.
Other reasons
- The server has not restarted. Settings apply when the server starts.
- The page refused a value. It tells you and saves nothing. Fix the value and save again.
