Robert, I am seeing the same issue. I have two companies on QBO - one of the companies includes a Project where the Overview tab is properly showing my expenses, income, and profit; one company has a Project that has the same problem you are/were experiencing. Did you figure out what the error was? I can see the transactions in the Transactions tab, but those transactions don't appear in the Overview tab as if they are not properly journaled to the Project.

I hope you found a solution to your issue! Its boggling my mind, because like you, I think I have followed the correct method.
