Bug in count Unassigned request

Bug in count Unassigned request

Good afternoon.
In itself in version 7503 has detected an incongruity in number of requests for unit. If to look in bookmark Home - Global View it is visible, what Unassigned - 5, but if to press on digit 5 (http://isd/DrillDownRequest.do? columnNames=Status, SITEID&columnValues=Open%23%24%230&viewName=Unassigned_System) that we get on bookmark Request and to us is visible- 4 Unassigned requests. Why there is a difference in 1one the requests?
