I did a quick check to try and replicate this on my D2 Bravo, but I wasn't able to. If this happens every time, can you detail the steps exactly? Here's what I tried:
1. From watch face, hold down the Direct-To (Back) button.
2. Selected an airport 16.5 nm away.
3. HSI page is displayed, waited for GPS ring to turn green.
4. Pressed Start button to begin recording.
Following these steps I wasn't able to replicate your issue, and the screens display as expected, only changing when commanded with the up/down buttons.
Cheers,
Douglas
