Comping drum takes - possible bug?

I first posted this in the Nuendo forum but got no response. maybe someone here can shed some light on this for me.
I am using Nuendo 11, but I don’t think this is specific to any version in particular.
I do a lot of real drum recordings and sometimes the drummers are not great and I end up with 20-50 takes of the drums. I have all the drum tracks in a folder and the folder is set to group edit (so any change on one track will be made on all the tracks. I find that this ONLY works if every track has the lanes OPEN. If a track does not have all the lanes showing, it will not accept the group change and then I will get a warning that the tracks are no longer in sync (or something like that. I can deal with it, but when I have 50 lanes for each of the 15 drums tracks, that’s a lot of scrolling up and down just to open and close them all.

Anyone else experience this? Is there a workaround. I hope I didn’t already ask this but maybe I’m losing my mind.
