TestFlight milestones missing from the Debugger SDK (PhoneGap)

Using TestFlight with PhoneGap application, testing on ipad. In the TestFlight SDK debugger, I can see events session_startand session_end, but NO CHECKPOINTS . In the Xcode debugger, I see checkpointspassed in the console log.

Any idea why breakpoints are not displayed in the SDK debugger?

EDIT (4/30/12): After some use of TestFlight, control points appeared on the screen. I do not know why the discrepancy.
