REST Sensor Using JSON

When I use the generic rest template channelDiscovery I get a large amount of channels that are displaying values I am after correctly using the Query

/api.o.j/network%3Brxes%3Btx%3Bcpu%3Btemperature%3Blocation.remote

ie:

However when I use my own template:

{
  "prtg": {
    "description" : {
      "device": "iDirect Web GUI",
      "query": "/api.o.j/network%3Brxes%3Btx%3Bcpu%3Btemperature%3Blocation.remote",
      "comment": "No comment"
    },
    "result": [
      {
        "channel": "Latitude",
	"unit": "degrees",
        "value": $["5"]["latitude"]
      },
      {
        "channel": "Longitude",
	"unit": "degrees",
        "value": $["5"]["longitude"]
      },
      
    ]
  }
}

I only get the first digit of the value displayed in PRTG, even when I change the channel decimal places to show all, it rounds to the nearest full number.

I'm not sure why this is. Is there anywhere I can view the channelDiscovery template?
