"productName" is not returned from Get Uses and Product Profile API

The API endpoint documented at:https://adobe-apiplatform.github.io/umapi-documentation/en/api/group.html, has mentioned that "productName" is returned for the group type: PRODUCT_PROFILE but we are not seeing that now in the API response.
It was returning the field "productName" till last week. 

Could someone please help us as why we are not seeing the product name in the API response?

We are seeing this issue with several accounts.
