An in-app purchase has been returned and is highlighted in the table below

I have created 3 Consumable In-App products in appstoreconnect. Among this, 2 of them getting approved and one is in 'In Review'. Then it has changed to 'Developer Action Needed'. An in-app purchase has been returned and is highlighted in the table below, shown at the top. Then I removed the 'Developer Action Needed' product from my list. I want to add a Screen shot and promotional images into approved products. But now all the fields are disabled right now. How can I set a screen shot and promotional image for the products?
