Variaudio: shift between the sound and the visual of the wave (waveform)

I try to use Variaudio and there is shift, in the editor, between the sound (still untouched) and the visual of the wave (waveform). At first listen is beautiful, but the second, it shifts, the sound begins before the wave. Never Melodyne would do that … I want to wait for ARA and give a chance to Variaudio version 10, but it starts badly! It’s not serious and professional. Solution? Or is it a bug?

For the benefit of users with this problem, Cubase’s technical support advised me to clear preferences and reconfigure them. It worked.
