When you view the dashboard segmented (E.g. Visitor location = US), then you click on a row to "Open segmented visitor log", the resulting visitor log is not segmented by the dashboard-level segment.
In the screenshot above, I would expect the visitor log to only show the visits that resulted in the 21 impressions. However I actually receive a list of all visitors that generated impressions for that content (a much long list)
Awesome, thank you!
