When you say the SKU is empty, are you referring to the server by any chance?
SKU is a property of the Azure SQL database and not the server itself.
Resource Type: "Microsoft.Sql/servers"
Resource Type: "Microsoft.Sql/servers/databases"
For Master DB, you might see that the sku name is system and not a recognized SKU
Please post a screenshot, if you are seeing different results.
