Amazon emailed me steps to create a price discount but after completing Step 1, I am not able to go to Step 2. Option of discard can be clicked but not step 2.

As per this Amazon email, I do not see option to "Search by product name, ASIN or SKU to Add products to your price discounts. Click Add on the parent ASIN to automatically add all its child ASINs to your price discounts. You can also add a selection of child ASINs under the parent."

What could be the problem?
