Quantize problem, please.

I have put a drum into a folder and now I am trying to group quantize it.
I have detected hitpoints for every tracks, anyhow I am using 3 elements for the quantize.
I don’t know why a “stereo kick”, even if it is on the slice preferences , doesn’t get sliced nor previewed on project widows vertical red/white lines.
Why?

Hi,

Is it alligned with the events of the other tracks?

Hello. In my opinion they are alligned.

Altrough I had a message from Cubase “some elements could not be in sync” when I clicked on group edit mode.
Do have I to sync them? If I do, how to sync them?

Thank you.

problem solved! https://www.youtube.com/watch?v=VD8lr2tT-Qw
