Back End endpoint sends duplicate values

[maxpatiiuk]

Back-end endpoints for the permission panel sometimes return a 400 response that looks like this:

{
  "missing_for_6": [],
  "missing_for_7": [
    98305,
    393217,
    425986,
    491522,
    524290
  ],
  "all_accessible_divisions": [
    2,
    2,
    32768,
    32768,
    425984,
    491520,
    524288
  ]
}

Notice the duplicate values in the all_accessible_divisions array. It does not cause a problem on the front-end right now, but may in the future, thus would be good to fix it
