SOLE TT8 - Different pace than Zwift

Today was my first run on Zwift with my SOLE TT8 treadmill. I connected the treadmill to the Zwift app and noticed that Zwift was always 2 or 3 seconds slower in pace than what is being displayed on the screen of the treadmill. I was under the impression they would be the exact same. Do I have something configured wrong in the Zwift app?
