data.cloudstack_instance filters not working [CS 4.21][CTP 0.6.0]

Hi, recently moved to terraform provider v0.6.0 and wanted to obtain IP address of instance nic.

I created instances using resource - works fine.

resource "cloudstack_instance" "controlplane" {
  count            = var.controlplane_count
  name             = "${var.cluster_name}-control-${count.index + 1}"
  service_offering = "CS"
  boot_mode        = "legacy"
  template         = cloudstack_template.talos.id
  zone             = var.zone
  project          = var.project
  uefi             = true
  network_id       = cloudstack_network.talos.id
  expunge          = true
  root_disk_size   = 200
}

Then I tried to obtain instance details using datasource:

data "cloudstack_instance" "controlplane" {
  count      = var.controlplane_count
  depends_on = [cloudstack_instance.controlplane]
  
  filter {
    name  = "display_name" # Tried also "name"
    value = "${var.cluster_name}-control-${count.index + 1}"
  }
}

But provider returns an error:
Error: No instance is matching with the specified regex

While it certainly exists and should match.
