Comping multiple tracks that are in a group problem

[no-xplode]

Hi all,

I just have a simple question that bugs my head and I don't know why its happening.
I am on Pro tools 9.0.6 native. I have enabled the "Loop recording creates new playlists" and the "separated region operates to all related takes" options.
I have created an edit group with drum tracks. Then I loop record.
Then when I open the playlists view and make edits these perform to all drum tracks as they should. After I press the "copy selection to main playlist button" on one of the tracks, but only that track's selection gets copied to the main playlist.
This also happens if I choose the Alternate Takes method for comping. The tracks are grouped but only one track gets comped, the rest stay intact.
Please try this yourselves.

Any solutions?
Thanks
