When I connect my Phantom to the Assistant to check on things, and then go to the tools area to do an IMU calibration I notice the two buttons for "Check IMU Status" and the "Basic Calibration" buttons are grayed out (not accessible). The tab for Advanced and the button "advanced Calibration" are accessible. If I do an Advanced Calibration the basic buttons do get activated, or if I wait long enough with the Phantom on, they will become activated. Is this normal? If its not, what could be causing the situation.
