No test definition shown when importing suite after reinstalling repository. (4231760)

I have exported my test suite and then reinstalled my repository. I then re imported the test suites into the same schema so that I can have all my test definitions again. But after a successfully noted import, the test definitions are still not listed for the suite. The name of the imported suite appears in the dashboard, but no test definitions.

Is there anyway of recovering the definitions? How are you suppose to back up test definitions and carry them over to a schema (either a different schema, or the same as first exported)?
