When viewing queries, the amount viewed is less than the amount it shows in the bottom right hand corner. Eg. when viewing a query, the list says that it has 38 calls, however, only 30 are showing in the list. There is no page 2.
We have seen problems like this occasionally on earlier versions of Service Desk, the cause is normally something to do with the conditions on the query, could you tell us what they are and which object the query is based on?
