Resource Management errors
We have noticed issues with the resource management page when looking at planned work etc. In short, it doesn't add up and doesn't match the Workload Balancer.
Example 1:

How does 7.5 + 3.5 = 11.02? This type of discrepancy occurs a lot.
Example 2:
For a task for a given week, Resource manager shows 0.75 and the planner for the same entry shows 0.73.
Any ideas as to what is happening and how to fix it?
Thanks in advance for any help.
