I am in the midst of upgrading to 5.3. Whenever I go into ReportBuilder, and create a new report with a specific name, Rational Change gives me something like csReport0.xml as the name. I am able to change the name of the report and save it off as something else (example: test.xml). However, what I end up with are two reports - the one named csReport0.xml and the one named test.xml.
What could be causing this behavior?
