Hello again,
One thing that I noticed when using Compose in Grouped mode is that it does not create a new unique piece out of several segments as the description says, instead of adds them in order in a strange way that appears almost as a glitch to me.
It is difficult to explain for me but the first Composed "Grouped "segment only contains one of the two segments, other composed segments contain both and than the last one only contains the second segment. Attaching picture for demonstration.
