Mad watts in FTP ramp test (companion app)

Disparity between required watts in the companion app for the ramp test in a workout programme (dirt destroyer) It starts at my current FTP after a warmup and increases by about 60 w each min up to 1800 w.

The FTP ramp test functioned as intended in game (see below) but both prior and during the workout the companion app displayed the incorrect wattage (see below) and asked for more power during the workout.
