when creating a discovery rule based on a http item i encounter weird behaviour

the LLD macro filter doesnt map the correct data from the json part to the macro

this is the data from the http item

{
  "data": [
    {
      "type": "storageUnit",
      "id": "Tapes_LTO8",
      "attributes": {
        "name": "Tapes_LTO8",
        "storageType": "Tape",
        "storageSubType": "Basic",
        "storageCategory": "TAPE",
        "okOnRoot": false,
        "stageData": false,
        "useAnyAvailableMediaServer": false,
        "accelerator": false,
        "replicationCapable": false,
        "replicationSourceCapable": false,
        "replicationTargetCapable": false,
        "snapshot": false,
        "mirror": false,
        "independent": false,
        "primary": false,
        "instantAccessEnabled": false,
        "isCloudSTU": false,
        "freeCapacityBytes": -1,
        "totalCapacityBytes": -1,
        "usedCapacityBytes": -1,
        "mediaServerDetails": [
          {
.........

using the filter "$.data[*].id" will return me a list of all the ID's in a json query tester like this :

 
[
"Tapes_LTO8",
"dd_6900_sma_stu",
"media02_bdisk_stu",
"media_msdp_stu",
"media01_bdisk_stu",
"dd_6900_atr_stu"
]
however it doesn't work, in zabbix to get the same result i need to use:
 
$..id
 
It doesn't make sense to me.
Is this a bug ? or is Zabbix doing something with the data that is not in the documentation ?
