Model Card not showing in console when created with sagemaker.model_card.ModelPackage module

Hello,

I recently found this article from AWS describing the creation of SageMaker Model Cards using the sagemaker.model_card.ModelPackage module, specifically the function from_model_package_arn.

We went ahead with this method and successfully created the model package object & the model card object using this. After we called the create function on the model card object we seen the ARN of the created model card returned to us but unfortunately we could not see this in the SageMaker management console (Governance -> Model cards).

We can see the model card listed using the AWS CLI command aws sagemaker list-model-cards and we can't figure out why it is listed here but not visible for us to see on the console. Further to this, if we modify the URL of an existing model card to point to the newly created model card with the above method then the page loads as expected but still remains unlisted in the model cards table.

Is this a known bug or are we potentially missing something?

We are operating using us-east-2 region. Any help on this matter would be appreciated as we are at a loss with trying to figure this out ourselves. Many thanks.
