What you expected to happen?
A full assets clean should occur

How to reproduce it?
Just run the following :
eksctl create cluster --config-file ./group-nodes.yaml
eksctl delete cluster --name=demo-cluster --region=us-east-1

group-nodes.yaml file

---
apiVersion: eksctl.io/v1alpha4
kind: ClusterConfig

metadata:
  name: demo-cluster
  region: us-east-1

nodeGroups:
  - name: ng1-public2
    instanceType: m5.4xlarge
    minSize: 2
    volumeSize: 50
    volumeType: gp2
    maxSize: 3
    allowSSH: true
    ami: auto
    labels:
      nodegroup-type: demo-cluster-workloads
    preBootstrapCommand:
          # allow docker registries to be deployed as cluster service
          - 'echo "{\"bridge\":\"none\",\"log-driver\":\"json-file\",\"log-opts\":{\"max-size\":\"10m\",\"max-file\":\"10\"},\"live-restore\":true,\"max-concurrent-downloads\":10,\"insecure-registries\":[\"172.20.0.0\/16\",\"10.100.0.0\/16\"]}" > /etc/docker/daemon.json'
          - "systemctl restart docker"

availabilityZones: ["us-east-1a", "us-east-1b"]

Anything else we need to know?
What OS are you using, are you using a downloaded binary or did you compile eksctl, what type of AWS credentials are you using (i.e. default/named profile, MFA) - please don't include actual credentials though!
