When using a single main(...) method to include multiple test classes within a single project the Tests panel of Creator shows only 1 available test class.  However, executing "Run All Tests" still gives results for all tests.  The attachment is a sample project that shows this issue as well as a screen shot of Creator (with only 1 class but all results). 

I did confirm this same behavior back to Creator 4.9.2 but did not test prior to that version.
