Primavera 8.1 Project Import Problems

I have exported both a project and its baseline from a v6.2 and imported into v8.1 and re-attached the baseline to the project.

When checking the projects financials from the v6.2 to the v8.1, I have noticed that the financials are different, the actual cost is identical, but the bugeted and remaining cost are different between the two projects.

I have managed to track which activities its doing this on, it seems its on activities when I have assigned a roles only, all resourced activities seem to be fine.

The activities that are wrong should have two roles assigned, but it seems to have only brought through one role with the import.

Does anybody have any idea why it might be doing this? I asked our programmer to have a look and he has said the export is fine, its the import or maybe some project setting.

Anybody????
