I'm having the same issue when using both the Excel Connector or when using the REST API
I filter by Iteration and Project.
For some reason, both add-In and REST API return some users that don't show up under same projects and Iterations in the UI when using the Track -> Team Status view.
This causes the capacity numbers to be higher than in Team Status.
I noticed that one user was returned 3 times under different child projects. Is the Team Status view doing any kind of filtering based on other criteria?
Please HELP.
