Visemes not showing up properly

Hi!  I am very new to CH, and I have an issue with lip-syncing and Visemes that I can't figure out--I have brought my puppet into the timeline, as well as the audio file I would like it to lip sync.  I then "Compute Lip Sync From Scene Audio," (with both the red dot next to the Audio Input and Keyboard Input) which works great.  There are a few mouth positions I would like to change manually though, so I then "Split Lip Sync Into Visemes" and now I see in my timeline next to Lip Sync>Keyboard Input (as a pulldown).  In the tutorials I have watched, it should say "Visemes" next to lip sink and then have a layer of editable Visemes.  But that isn't showing up for me.  When I pull down the Keyboard Input layer, i get all the Visemes (each on it's own layer...so it's a VERY long scroll down)...and they aren't editable.  I can change their length, but it doesn't show the sound that each viseme is making nor does it allow me to change them.  What am I doing wrong?  I can't find the solution to this problem anywhere!
