Terraform helm_release destroys all other helm releases

Question

We have three services that we are trying to deploy to a k8s cluster with Terraform helm_release. Each service has something similar to

release.tf

resource "helm_release" "someService" {
  count = var.deploy_apps ? 1 : 0
  name = "someService"
  version = "2.1.3"
  namespace = "app"
  timeout = 600
  values = [yamlencode({
    image = {
      tag = var.terraform_version
    }

    envVars = {
      k8env = local.environment
    }
  })]
}

variables.tf

variable "deploy_apps" {
  type = bool
  default = true
  description = "deploy someService"
}

With the only difference being the service name. Each service is in its own Git repo, each repo has its own variables.tf file which contains its own deploy_apps variable, and they are all deployed to the same namespace.

When any of the services is deployed, it destroys the other two.

How can we prevent that from happening?
