Hello there, tmullins.

You'll want to check if the items are assigned to the correct class. After modifying the items, run again the Profit & Loss Budget vs. Actual report. If it's still showing on the wrong class, you can run verify and rebuild data to check possible data issues in your company file. 

After running this tool, open the report again.

If you have further clarifications with your financial report, you can always reach out to me.
