On the workout screen, when the target power is defined as "Over-xxx W" (example is in Garmin's own plans, workout "Fitness Test (3 Min. + 10 Min)"), the graph during this step of the workout shows 2000+ W.
This makes all the other steps with more reasonable power unreadable, since Y axis is scaled to 2000+ W.
I suggest to show the target on the screen as xxx when defined as "Over-xxx W".
