I don't know if this will help anyone, but one of my classes out of several was not showing up on reports - only one! I intuitively figured out that it was becuase it was the same as one of the "names" in my company. When I changed the class name to be something different, it now shows up on reports. I have Mac Desktop 2024 QB. I would not think this would have been a problem, but it was and now it is resolved.
