When building a report, you first add several widgets to the report. This is done by choosing Add Widget and choosing Project, Portfolio, or Target, and then choosing the widget you would like to add.

Once you add the widget, and go to add another one, you must reselect the Project, Portfolio, or Target.

Since users will likely require multiple widgets for the same property, it would be nice to retain the selection between adding widgets so users can rapidly build out their report.
