Kingslake FTP test issues

Did the Kingslake FTP test. Did not show the countdown clock (on screen or HUD) during the 20 min segment, although I did get the audible cues. I got the announcement that the value was updated, but when I checked it in the settings, it hadn't changed. Importing the ride into golden cheetah software, got the average power over the test segment and calculated the FTP using the Fulgaz formula. My FTP had in fact increased 5 units. Win 11, Fulgaz v7.0.7.0
