Progress bars on Road Map have wrong estimates

When viewing the Road Map of a project, and hovering over either the resolved or unresolved issues on a progress bar, the number of issues that it says are in that section is not the same amount as the number of issues that are listed in the filter when clicking on the link to that section.
Example: On the progress bar it says 7% (20 issues) for Unresolved issues. Clicking on that part of the bar leads to the Find Issues page with 52 results.
