Please ignore above reply, it sees @mk has not understood the question properly.
The Course and product is integrated by default. The question has a lot of information missing so I am assuming few things :
- You're talking about front end course creation - pricing section.
If you edit the Course - pricing section, the Instructor sees the product title. This is required for new course, currently many users build product bundles, so the product title is relevant field. For example, an Instructor can associate 1 product with two of its courses and then both the courses can be subscribed simultaneously.
Of course, the product title field can be hidden and automatically set to course title but it will strip down the flexibility of creating course bundles as well.
