Azure App Config Deployments are not working as expected

Hi ,
Greetings!

We are trying to use the GitHub Action as well as Azure CLI to deploy the App Configs in Azure Cloud but we are not able to update the configs and it's expecting us to delete the existing configs and deploy again.

Here is the GitHub Action we are trying to use:
uses: Azure/app-configuration-import-action@v1.0.0
with:
name: ${{ inputs.AppConfigurationName }}
path: '${{ inputs.ServiceName }}/config/app.yml'
prefix: '${{ inputs.ServiceName }}/'

Here is the Azure CLIs we are trying to use:
az appconfig kv import --label test --separator '.' --name ${{ inputs.AppConfigurationName }} --source file --path ${{ inputs.ServiceName }}/config/application.yml --format yaml --import-mode ignore-match --strict false --content-type application/x-yaml --yes

az appconfig kv import --separator '.' --name ${{ inputs.AppConfigurationName }} --source file --path ${{ inputs.ServiceName }}/config/application.yml --format yaml --import-mode ignore-match --strict false --yes

Can you please this issue at the earliest and suggest on how to deploy/update the App configs instead of Deleting them every time and then re-creating again?
Can you suggest solution, this is a blocker for us to proceed.
