How can i parse the checkbox value using SenseML nearestcheckbox method

Question

I am using SenseML to parse PDF checkbox value by using nearestcheckbox method using the below configuration, but I am unable to parse the field. The anchor is not selecting the expected filed. Please see the attached image for reference.

{
  "id": "virus_incidents.no",
  "method": {
    "id": "nearestCheckbox",
    "position": "left"
  },
  "anchor": {
    "start": {
      "text": "an incident response plan for network intrusions and virus incidents?",
      "type": "includes"
    },
    "match": {
      "text": "No",
      "type": "includes"
    },
    "end": {
      "type": "includes",
      "text": "If the Applicant has a business continuity plan, does the plan contain recovery time"
    }
  }
}
