There are a few reasons why the Project Detail cost report doesn't match the project cost, Mary.
One reason is how transactions are recorded and allocated. Could you share a bit more about how you're recording your transactions and items for these projects?
To make sure the totals add up correctly and aren't being duplicated, review the transaction entry and double-check that the amounts are proportionally allocated to respective categories.
Also, know that there are times browser-related issues interfere with project management systems and cause reporting modules to generate incorrect totals.
