Hello, DanOR.

Thanks for following-up with us. I also appreciate your time doing what my colleagues had suggested. 

What my colleague meant to say was that you'll want to check the item's settings to see if it's mapped to an account correctly. This might also be the reason why the quantities show different on the detailed and summary reports. 

Also, I agree that breaking down the issue can save us some time. I did review the parts of your PDF file and it looks like an inventory quantity adjustment was made and mapped to a different account. In this case, you'll want to check the Inventory Valuation Detail report and look for the adjustment transaction. 

You can also search for it using the magnifying class icon: 

1. Click the magnifying glass icon.
2. At the bottom, click the Advanced Search link.
3. Under Search, select Inventory Quantity Adjustment.
4. Set the second drop-down menu to Product and Service.
5. Under the last drop-down menu, select the product (Beef + Potato in your case).
6. Hit Search.

Inventory adjustments can be tricky, so I recommend working with an accountant for corrections. If you need a brief guide, you can check this article: Adjust inventory quantity on hand in QuickBooks Online.
