Thank you DivineMercy_N for your response. I followed up on your recommendation yesterday and worked with two QBO Support Team members yesterday. Both were very helpful. After reviewing the existing transactions and even redoing all the transactions, the conclusion reached is that we "think" the transactions are properly linked and that there is a "software glitch" occurring.

But before I request Intuit software engineers to get involved, I've decided to post the current situation here along with png files so anyone who might reviews this situation may be able to figure out where I may have made a data entry error.

I've also discovered that only one png file can be uploaded per each post. So the information i am presented will be provided in five posts (including this one).

The first file is the P&L Report by Class - this is where part of the problem lies because if the standard report were run, unless you happened to click on the 0.00 total you would not even have noticed there are transactions showing up in different classes that are associated with this one issue. And yes, every line item of every transaction has the same identical Class assigned to it.
