export of a view in 9.2.0.3 and imported to version 9.2.0.8 changes its definition

I wonder why the imported view from production (version 9.2.0.3) changes this line in Uat datbase (version 9.2.0.8)
In prod - this line:

AS
   SELECT ASAP.TASK.*
     FROM ASAP.ACCESS_SERVICE_REQUEST, ASAP.TASK

In Uat changed to this after import:

AS
   SELECT ASAP.TASK."DOCUMENT_NUMBER",
          TASK."TASK_NUMBER",
          TASK."TASK_STATUS",
          TASK."TASK_PRIORITY",
          TASK."SCHEDULED_COMPLETION_DATE",
          TASK."ACTUAL_COMPLETION_DATE",
          TASK."ESTIMATED_COMPLETION_DATE",
          TASK."LAST_MODIFIED_USERID",
          TASK."LAST_MODIFIED_DATE",
          TASK."TASK_TYPE",
          TASK."CIRCUIT_DESIGN_ID",
          TASK."WORK_QUEUE_ID",
          TASK."WORK_QUEUE_PRIORITY",
          TASK."ASSIGNED_FROM_WORK_QUEUE",
          TASK."ASSIGNED_FROM_DATE",
          TASK."TASK_STATUS_DATE",
