Open and run (preview) a database query. The query data then changes. Run the query again and the preview data does not change. This issue is under investigation.
This issue only affects the previewing of the data. The issue does not affect the results of the query when it is used in a Burst, XDC, etc. The query will run and return current data. To work around the data preview issue, log out of the user interface, log back in and run the query again via the Database Connection.
