Minikube kubernetes - (kube-proxy) configmap update compacts text

Question

Issue: editing the Kube-proxy configmap via kubectl directly or applying a new configmap via kubectl apply -f kube-proxy.configmap.yaml causes the configmap to become formatted into a condensed version preventing future edits.

System:

• minikube: 1.32.0
• kubectl:

  Client Version: v1.29.1
  Kustomize Version: v5.0.4-0.20230601165947-6ce0bf390ce3
  Server Version: v1.28.3
  

• kube-proxy: image: registry.k8s.io/kube-proxy:v1.28.3

Originally the configmap looked like this:

apiVersion: v1
data:
  config.conf: |-
    apiVersion: kubeproxy.config.k8s.io/v1alpha1
    bindAddress: 0.0.0.0

I used the normal process of updated a configmap and now when i edit the configmap again it looks like this:

apiVersion: v1

However when i describe the configmap it looks like the original. Is there an issue with how minikube, kubectl, or an update i am not aware of that is compacting or condensing the configmap?
