Adding new API Version to Azure API Management

I am creating a new version of an existing API on SwaggerHub and set up integration with Azure API Management instance. After I save this new version on SwaggerHub, I am expecting it to appear on  Azure API Management. But it doesn't. I only see the earlier version, which already existed before.

Also, for the new version I made sure the value for x-azure-api-id is not populated, so that the app knows its a new version.  I also tried retaining the x-azure-api-id same as earlier version. Nothing happens and there are no integration errors. Am I missing something here?
