Report Filters - Bug & not?

Did we change the logic and/or purpose of the Top Filters in a report. Like for instance, in the Stock Balance Report has From Date, To Date, Item Group, Item and Warehouse as the filters, so, if I select a particular warehouse on the top filter, the report should only display the balances in that warehouse, right?

But I am able to see all warehouses on an instance that is on AWS.

Is that a bug, or did we change things?
