P&L expenses compared to Expense report

Hi.

Using QB online. When I run a report from the Expenses tab on the left side of the home page and included all transactions, it produces a report showing Bills, Bill Payment (Checks), Checks, Credit Card Expenses, Expenses and Vendor Credits. 

In theory, it seems that the sum of some combination of those categories (I would think it'd be all of them expect Bill Payment (Checks)) should match the Expenses amount from the P&L... but it doesn't and I can't figure out why.

Thoughts?

Thank you.
