For me, switching the type of Console Emulation in quick grouped tracks was always a little funny. It wasn't absolute. If you 2 were A and 1 was N and you quick grouped all three and moved the A to N, the Ns would become S.
In other words, it moved them all and relative to their current position.
This is how it works for me as well. It would be better to have the selection be absolute (go to type A if I click type A on one channel) and not relative.
Other than this I also found a bug that is repeatable on my system running X3c. Open a new project and upload a few audio files as separate tracks. Now group the tracks and use CTRL while selecting a new CE type in the pro channel. On my system the first click to a new CE type results in only the CE on the one track that is highlighted turning *on* (no change to the CE type). The second click results in a change to the new type, but only to the one track actually highlighted. This applies to making changes to the drive as well. It acts as if nothing is grouped.
Now, try grouping the tracks and clicking the on/off button. This seems to "reset" things and suddenly grouping and controlling things like CE type, drive etc. work as expected. From this point on everything works ok, even if I turn CE off on all tracks, save, and then reopen.
Odd, and clearly a bug. I will report it.
On perhaps a related matter, trying to work with projects started in X2 results in very odd, seemingly unpredictable behavior similar to what others have described.
