Your budgeted values and baseline values should/could be the same. But if you start changing the current project's budgeted units/costs, they will be different. But since your baseline values aren't giving you the expected results, I would look at Admin Preferences -> Earned Value (tab) -> Earned Value Calculation (drop-down). At Completion Value or Budgeted Values are the 2 choices. Perhaps it's using At Completion Values and those are not the same as the Budgeted Values?
