Custom Common Data Model not showing up in list?

Hi

I have created a model.json that describe a CDM for "Prod" (just for test purpose). I have connect the PowerBI to Azure ADLS 2 with hierarcy enables. I have uploaded the model to Container. I have attached the model to the Power BI Workspace.

Now, I would like to map my data to the model within the Dataflow operation. However, my model does not show up in the list of models. How is that?

My Model: 

{
"application": "MyApplication",
"name": "Prods",
"description": "Model containing data for Order and Products.",
"version": "1.0",
"modifiedTime": "2018-01-02T12:00:00+08:00",
"entities": [
{
"$type": "LocalEntity",
"name": "Products",
"description": "Information about products and their pricing information.",
"attributes": [
{
"name": "productId",
"description": "The unique identifier of the product.",
"dataType": "string"
}
]
}
]
}
