Multi-select Filter in ag-grid-angular

I have a multi-select filter option on top of my ag-grid table. If I select 3 options out of them, the filter set to the model is given below. But ag-grid is not applying all the 3 options. It applies only 2. Is this a limitation of agNumberColumnFilter in ag-grid-angular ?

{
  "filterType": "number",
  "type": "number",
  "operator": "OR",
  "conditions": [
    {
      "type": "lessThan",
      "filter": 2
    },
    {
      "type": "inRange",
      "filter": 2,
      "filterTo": 5
    },
    {
      "type": "inRange",
      "filter": 6,
      "filterTo": 15
    }
  ]
}

Below is my ag-grid-angular and the definition for the column I am applying this filter for.
