Orphaned nodegroup keeps creating EC2 instance

Hi,

I created an EKS cluster with Terraform. After destroying it with Terraform, I still have an orphaned nodegroup that I cannot see in the dashboard nor with awscli.

And this nodegroup keeps creating an EC2 instance. If I delete the instance, the nodegroup creates a new one.

This is generating billing costs for resources I am not using.

Any adivice?

Thanks
