Where is the "AI Suggested HS Code" in V5 Shipping Manifest? Why can't the last box be clicked?

1. In the shipping items of Shipping Manifest "SIM-SHP-S0020-01", open the item row with SKU "DL-HS-AL". 2. When the company has set up an AI key, you can see the clickable "AI Suggested HS Code" button and related instructions; this test did not click it, so there is no actual AI response available for reference. 3. The "AI Suggested HS Code", "HS Code Number", and "HS Code Description" in the last box row are all in disabled state and cannot be operated.
