Step Sequencer not showing notes in existing clips

Hi,
Newbie here. First post.  I did look for this answer, and read the tech ref, but i'm stumped.  I'm running X2a and I open a new project, insert Superior Drummer, create a step sequencer pattern, play it back, etc, everything is fine.  Then I x-out of step sequencer and can see my clip with data in it in my track.  If I load the piano view on that clip, I can see my notes.  But if I double click on it, when step sequencer comes up, the matrix is blank.  My notes are not there.  It's like it loaded a new SS clip/window. I'm sure it's just a setting, but I can't find it and it makes no sense to me as a default behavior.  8.5PE didn't work like this.  Please help.
Thanks.

If I drag the clip into the SS window, the notes show up for that instance only.  If I close the SS window and double click on the same clip again, the notes do not appear.

In another thread you mention using a drum map.  I have read about problems using drum maps and the step sequencer in X2 (apparently confirmed by CW). You are better off not using a drum map if you intend to use the step sequencer.

Do not use a drum map if you plan on using the step sequencer in X2 or X2a. http://forum.cakewalk.com/FindPost/2901903

just double click the ss clip twice.
and yes, drum maps work fine...

I wish they had put a kb article up about that. I havent had any issues...

I seem to be in Bob's camp.  Swamptooth, can we do a quick test?  Can you open a quick test project, insert a drum program(maybe session drummer since we both have it), point the midi track's output to a drum map, open step sequencer, create a sample pattern, close SS, and then double click on the clip to see if the notes show up?  I'd like to try the exact same experiment as you to see if it's some other variable.
thanks.

Ok, thanks.  That actually doesn't work for me.  Or it might work once, but doesn't the next time.  If you subsequently close that ss window and double click on the clip again, do the notes appear or do you need to select SS from the drop down menu every time?

I believe my suggestion was to double click the clip once which will open step sequencer, then wiith step sequencer open double click the same clip.

Saints be praised.  Both ways work.  Double clicking the clip again puts the notes into the SS window.  And selecting SS from the top right icon, after SS window is open, also populates the notes.  I'm ok with this one extra step.  I'll use the double clicking twice method.  it's unfortunate it doesn't just work like it did in 8.5, but it's close enough. 
Thanks everybody! Now back to the music.

and it comes full circle
