You can get strange results if Dispatcher and its Nodes are not connected to the same database. Dispatcher and Nodes might be also connected to a different database than the one you are monitoring.
Please check that configuration files for Dispatcher and all Nodes contain element /innovatrics/idkit/dispatcher/database (for Dispatcher) or /innovatrics/idkit/node/database (for Node) that contains element "type" with value "odbc" and identical settings for ODBC parameters (dsn, username, password). Also check that the ODBC DSN is configured identically on all Node machines as well as on Dispatcher machine.
If this doesn't help, try to enable debug output on Dispatcher and Nodes to see more details about transactions performed by ExpressID AFIS.
