Duplicate images coming with <none>:<none> tag

[sakshiarora13]

Description

I am trying to bring up kubernetes cluster with containerd and nerdctl.
After bringing up my cluster, I am able to see duplicate entries for nerdctl images

After analyzing, I saw that there are 2 entries for an image ID. One with actual name:tag and another with none:none

What is none:none and how can i avoid this?

Steps to reproduce the issue

1. Pulled images from internet registries
2. Installed Kubernetes and initiated services
3. Run nerdctl images

Describe the results you received and expected

Received: Multiple entries for a single image ID
Expectation: No none:none entry should be there

What version of nerdctl are you using?
