P6 locks up when trying to open the Resource Usage Profile

Background

We are using P6 8.2 EPPM.

By design, when a cost is entered without a resource, the costs will not show up on the Resource Usage Profile.

We us Lump Sum resource and Non-labor Costs for our costs. We do not use units.

How the problem started

I have a schedule that a Project Manager cost-loaded without assigning a resource first, and the Resource Usage Profile opens but no histograms show up. (We are required to provide a Resource Usage Profile for this Project.)

In an effort to fix this, I created a User-defined field for costs and opened it up next to the Budgeted Non-labor Cost column so I could duplicate his costs for re-entering. I then entered in the cost he had in the Budgeted Non-labor in the User-defined column.
