Resource group name auto generated

[metabsd]

Hello I am a beginner with this great module. I would like to understand better how to use it. For example I try to create a resource group but the name seems to be auto-generated. I would like to control the prefix and the name of the resource group.

module "caf" {
  source = "aztfmod/caf/azurerm"
  providers = {
    azurerm.vhub = azurerm.vhub
  }
  global_settings = {
    default_region = "region1"
    regions = {
      region1 = "canadaeast"
    }
  }
  resource_groups = {
    test = {
      prefix = "rg-s-s"
      name = "test"
    }
  }
}

Output:

module.caf.random_string.prefix[0]: Refreshing state... [id=myvp]
module.caf.module.resource_groups["test"].azurecaf_name.rg: Refreshing state... [id=goeepmdolxdesrbf]

Expected resource group name: rg-s-s-test
Actual resource group name: myvp-rg-test

Help :)
