Inventory - cost value missing for some inventory items

I used batch create to upload my inventory items. Afterwhich, I set the starting balance for inventory items using batch create. However, some items’ cost are not showing up under Summary → Less Expenses → Inventory - cost after receipt is issued. Sold product’s values for Inventory - sales are correctly recorded and displayed.

Any advice on how to troubleshoot the issue would be greatly appreciated!

Thank you.
