Gear Shifting Issues - Hammer 3

I have done only open riding on Zwift on a Hammer H3 via the Android Zwift App. My experience so far, suggests the watts, cadence, and speed seem to be comparable to a real ride. Good news. However, I find that down shifting is strangely completely unnecessary when climbing. As the incline increases, the speed goes down, but the resistance doesn’t change significantly, so there is no need to down shift. Is this normal? Or have I screwed up a setting?
