Financial Plan - Maintain Budget has different value to Budget lines

Hi,

      my client has baselined a Financial Plan which shows the Raw Cost and Burdened Cost sum as $755k (on the Maintain Budget Version screen). However, when they drill down to the Budget Lines the Cost is summing to $573k, across Task range 1.x and 2.x (although there are Budget values against Task 3.x, 4.x and 5).

When I first looked at the Baselined Version the Task Structure only included 1.x and 2.x. At the top of the page it indicated that the WBS had changed and to run a particular PRC to update. Once they had done this the Tasks showed on the screen but the budget amounts are still not aligned - at the Budget line the values for Tasks 3.x, 4.x and 5 are still not showing?
