Have you logged out and logged back in? If not, try it and see if you find anything. The Profit & Loss by Class should show you all the items in the column for the Class. You can also Filter the Report to show only that Class.
Does the Name show up, but there's just nothing shown? If you really don't see anything, go change the name to something else. Then change the incorrect spelling to the correct spelling.
Also, try running Utilities and Repair the File. There may be something just hung up. (After you do a backup, of course...)
