Prologue VCO's not in sync


I’m new here. I’m using Cubase elements 10 trail version.
I want to edit a prologue sound and want to start with 2 saw waves in tune and then a little bit detune to make a phat saw sound, but I’m not able to tune 2 oscillators. I set both osc’s on 0 and It looks like the frequency is different on both oscilators. How can I tune a 2 OSC sound ?
