no longer closes automatically

After 1.2.4 it doesn't automatically close the time to wipe status bar after 5 minutes of joining the server but stays there.
Here is my config file :

  "Status display time in seconds (0 - unlimited)": 300.0,
  "Only show in authorized cupboard area": false,
  "Update Interval (in seconds)": 60.0,
  "Icon Url": "default",
  "Time Format": "d\\d\\ hh\\h\\ mm\\m",
  "Colors": {
    "Color": "0.5 0.5 0.5 1",
    "Icon Color": "1 1 1 1",
    "Title Color": "1 1 1 1",
    "Text Color": "1 1 1 1"
  }
}
