Logic Pro X MSEG sync division problem (Alchemy)

Roman Che

Hi friends.
I have the problem with Alchemy. I can't find anything in the internet and in the Help, this is why I'm here.
Look what I mean:

How can I change divisions rate ? I mean not just scale, I mean sync to tempo rate 1/16, 1/8, 1/32...
Cheers, Roman
