If I use a selective phaser on a group of sunstrip.
I take the 1st half of this group, I change the phase then I try to make 2nd half of group AT 1st half of group.
It does not copy me the new phase and gives me the beginning effect.
And if in the clone options I click on high then even the 1st part of the group returns to the original effect.
Normally I don't need to extract the values since the new phases are not marked as a preset.
If I do it with a universal phaser the copy goes well.
