harmonies sound pretty weird. Voicelive touch 2

Contributor - Level 1
i've had a Voicelive touch 2 for about 2 months now. so far i've dealt with the different settings. I also tried out the presets that came with it. Unfortunately, the harmonies sound pretty weird.
I haven't found a preset suitable for the choir of the song "California dreaming" by "The Mamas & the Papas". I use "roomsense/auto" and am accompanied by a guitar.
Do you have a suggestion as to which setting I should make?
Please excuse my poor English.

Yours sincerely
