Actual and remaining work problem

[Guidho]

I have a couple of projects, let's say A and B.
In this projects, I have a resource R which was set to inactive.
I noticed that this resource still has some remaining work, so I
re-activated the resource to set remaining work to 0.

But I ran into this problem:
I open project A in MSP Pro. Resource R has two assignments (in resource
usage view). One from project A and one from project B.
For the external task from project B it says:
- Work: 45days
- Remaining Work: 45days
- Actual Work: 0days

Now, I open project B to set remaining work to 0 for resource R. But what
does project B tells me?
- Work: 45days
- Remaining Work: 0days
- Actual Work: 45days

I open PWA with resource R account. This also shows that remaining work = 0.

I have reset remaining work in project B to 0 and republished, but the
problem still exists.

Any suggestions? Thx!
