Describe the bug This bug is still present: https://github.com/rancher/rancher/issues/36197

These steps are all in the ui:

3. bootstrap the cluster as told in the ui
4. generate a random password
5. create a new cluster with RKE
6. use a random name for the cluster
7. merge the encryption config from https://rancher.com/docs/rke/latest/en/config-options/secrets-encryption/
8. selecteer all rollen
9. click op done
10. edit the cluster as yaml
11. click on save
12. edit the cluster as yaml

Result

The config at step 10:

resources:
  - providers:
      - aescbc:
          keys:
            - name: k-fw5hn
              secret: RTczRjFDODMwQzAyMDVBREU4NDJBMUZFNDhCNzM5N0I=
        aesgcm: {}
        identity: {}
        kms: {}
        secretbox: {}
      - aescbc: {}
        aesgcm: {}
        identity: {}
        kms: {}
        secretbox: {}

The config at step 13:

resources:
  - providers:
      - aescbc:
          keys:
            - name: k-fw5hn
              secret: RTczRjFDODMwQzAyMDVBREU4NDJBMUZFNDhCNzM5N0I=
        aesgcm:
          keys: null
        identity: {}
        kms:
          endpoint: ''
          name: ''
          timeout: {}
        secretbox:
          keys: null
      - aescbc:
          keys: null
        aesgcm:
          keys: null
        identity: {}
        kms:
          endpoint: ''
          name: ''
          timeout: {}
        secretbox:
          keys: null

Expected Result

The configuration should be the same as on stap 7 and thus the configuration on this page: https://rancher.com/docs/rke/latest/en/config-options/secrets-encryption/
