Night Duration is wrong

I would like to configure the plugin as follows:

• Default rust day/night cycle of 45 minutes day, 15 minutes of night
• Allow players to skip night (I would expect the night to be shortened to 3 Minutes)

My configuration:
 

  "Time Settings": {
    "Day Start": "07:30",
    "Night Start": "19:30",
    "Voting time": 60,
    "Voting start time (time to check)": "19:00",
    "Time until which hour the voting will take place (time to check)": "20:00",
    "Time after voting (to which the night passes)": "7:30",
    "Fast skip the night": false,
    "Length of the night (minutes)": 15,
    "Length of the FAST night (minutes)": 3,
    "Length of the day (minutes)": 45,
    "The number of skipped nights, after which it is impossible to skip a single night?": 0,
    "Night with a full moon": false,
    "Full Moon Dates": [
      "2024-01-25T00:00:00",
      "2024-02-24T00:00:00",
      "2024-03-25T00:00:00",
      "2024-04-23T00:00:00",
      "2024-05-23T00:00:00",
      "2024-06-21T00:00:00",
      "2024-07-21T00:00:00",
      "2024-08-19T00:00:00",
      "2024-09-17T00:00:00",
      "2024-10-17T00:00:00",
      "2024-11-15T00:00:00",
      "2024-12-15T00:00:00"
    ]
  },
  "Votes Settings": {
    "Vote Commands": [
      "voteday",
      "vt"
    ],
    "Chat notification when voting starts": false,
    "Number of votes": 0,
    "Use a percentage of the online?": true,
    "Percentage of the online": 50,
    "Commands after lost voting": "",
    "Commands after successful voting": "",
    "Enable a voting fee for skipping the night?": false,
    "Refunds if a vote is canceled?": false,
    "Cost of skipping the night": 100
  }

Outcome:
* Unskipped night only ~6 Minutes instead of 15 Minutes
* Day seems faster than 45 Minutes as well, but I did not take a measurement
