No fields or product attributes are showing on add product/edit product

Hello,
I have installed a fresh Drupal Commerce and enabled all its sub modules. After enabling, i have created a new store and when i tried to add a new product, it is only showing option for Title and description. There are no further options available on screen. All i can see on screen is like this:

I have un installed and re-installed Drupal commerce to fix this issue but it still exists.

Steps to reproduce

1- Install Drupal Commerce
2- Install required modules & libraries.
3- Install & Enable all sub modules of Drupal commerce (Commerce, Commerce orders, Commerce cart, commerce products etc).
4- Go to Commerce ->Configuration -> Store & create a store.
4- Go to Commerce -> Products -> add new.
5- On next screen you can only see two fields. There are no product fields like Product price, Product category, Product Images, Product variations etc.

Please tell me what i am missing in above steps for getting full view of all fields on Add product screen.

Proposed resolution

There should be Product fields on next screen like Product price, Product category, Product Images, Product variations, Product Regular & Sale price, Product Weight, Product SKU etc.
