Multiple Events running

I have set the config to only run one event at a time but it runs 3 to 4 events at once. 

{
  "Event Timer Interval (In Seconds)": 1,
  "Event Notification Timer (In Seconds)": 300,
  "Notify on crate hack to all players": true,
  "Event conclude on Hackable Crate loot": true,
  "Event conclude countdown on Hackable Crate loot": 5,
  "Event Owner Settings": {
    "Enable event owner based on npc damage?": false,
    "The amount of damage that the player has to do to become the Event Owner": 500.0,
    "Send Console commands on event won by player": false,
    "Console commands list(Placeholder: {PlayerSteamID})": [
      "sendmenudes {PlayerSteamID} 100"
    ],
    "Can the non-owner of the event loot the Hackable Locked crates": false
  },
  "Chat Settings": {
    "Chat Avatar Icon": 0,
    "Chat Prefix": "<color=#FFFF00>Monument Events</color>: ",
    "Chat Notification Type(CHAT/TIP/BOTH)": "BOTH"
  },
  "Scheduled Events": {
    "Enabled": true,
    "Minimum Time Between Events [In Seconds]": 3600,
    "Maximum Time Between Events [In Seconds]": 3800,
    "Max Events On Server At Once": 1,
    "Minimum Required Players Online": 1,
    "Spawn Event From The Schedule Events List": true,
    "Schedule Events List": [
      "airfield_1",
      "launch_site_1",
      "trainyard_1",
      "junkyard_1",
      "harbor_1",
      "harbor_2",
      "powerplant_1",
      "water_treatment_plant_1",
      "sphere_tank",
      "satellite_dish",
      "ferry_terminal_1",
      "gas_station_1"
    ]
  },
  "Version": {
    "Major": 1,
    "Minor": 1,
    "Patch": 6
  }
}

Hey, based on the config its not possible to start 2 3 events on the server unless you are manually starting the events with commands. Please check if you have set up Event automation with commands on other plugins.
