A4t vs Adobe Target Reporting Numbers: Conversions

Hello,

  Regarding Adobe Target a4t I see a test that has activity conversions higher in workspace than the conversion number that inside the Target interface.

How did I get these numbers - Adobe Target interface (in reports - number next to conversion %) compared to A4t the activity conversions metric in workspace.

 Its easily over 500 more. Which for our test means quite a bit. We set the reporting for this test to be in analytics... but I'm an admin in AA and see both.

 Could you help me understand why I see such a difference in conversion numbers?

Thanks
