Import G-Metrix from another source = Stabilization no longer available / Virb 360

On Virb 360 with GPS on and then reviewing the video, everything is smooth and stabilization is working perfectly. When I import G-Metrix data to get additional data points from either a Fenix or a Garmin Edge all stabilization is lost.  All various stabilization options have no effect. Even when I revert all data points back to Virb360, the video still has no stabilization.  All software/firmware is up to date.
