"nsxt_policy_tier1_gateway" preferred_edge_paths [] ignores order of provided edge TN pathes

[benzander]

Describe the bug

I've tried to use preferred_edge_paths in the ressource "nsxt_policy_tier1_gateway" to set a preferred and a secondary edge TN.
As that is an array I would expect the TF provider to use the first element as preferred Edge and the Second element as secondary edge. But it ignores the order of elements.

Reproduction steps

here my Ressource:

resource` "nsxt_policy_tier1_gateway" "t1" {
  display_name = var.displayName

  locale_service {
    edge_cluster_path = var.edgeCluster.path
    preferred_edge_paths = [
      "/infra/sites/default/enforcement-points/default/edge-clusters/6f5904a3-f63f-484c-bbe6-f48901e7918d/edge-nodes/1",
      "/infra/sites/default/enforcement-points/default/edge-clusters/6f5904a3-f63f-484c-bbe6-f48901e7918d/edge-nodes/0"
    ]
  }

  tier0_path                = var.t0.path
  route_advertisement_types = var.routeAdvertisement
  pool_allocation           = var.poolAllocation
  default_rule_logging      = "true"
  enable_firewall           = "true"
}

Here how the plan looks like:

~ resource "nsxt_policy_tier1_gateway" "t1" {
        id                        = "7be7c794-4d57-4baf-818c-10b3db944a46"
        # (15 unchanged attributes hidden)

      - locale_service {
          - display_name         = "34206d27-1765-4802-b84a-4f6e3a183764" -> null
          - edge_cluster_path    = "/infra/sites/default/enforcement-points/default/edge-clusters/6f5904a3-f63f-484c-bbe6-f48901e7918d" -> null
          - path                 = "/infra/tier-1s/7be7c794-4d57-4baf-818c-10b3db944a46/locale-services/34206d27-1765-4802-b84a-4f6e3a183764" -> null
          - preferred_edge_paths = [] -> null
          - revision             = 1 -> null
        }
      + locale_service {
          + display_name         = (known after apply)
          + edge_cluster_path    = "/infra/sites/default/enforcement-points/default/edge-clusters/6f5904a3-f63f-484c-bbe6-f48901e7918d"
          + path                 = (known after apply)
          + preferred_edge_paths = [
              + "/infra/sites/default/enforcement-points/default/edge-clusters/6f5904a3-f63f-484c-bbe6-f48901e7918d/edge-nodes/0",
              + "/infra/sites/default/enforcement-points/default/edge-clusters/6f5904a3-f63f-484c-bbe6-f48901e7918d/edge-nodes/1",
            ]
          + revision             = (known after apply)
        }

        # (1 unchanged block hidden)
    }

Expected behavior

I would expect the Terraform Provider to use the order of elements provided
