As u can see the 2nd chain doesn't display properly.

I dragged the detail view closed and opened it again to see if that would reset it, but that spread the bug to both chains as seen below

hope this hasn't been reported already
Edit:
I had also changed the receiving note on the 'Tom 808 Mid' pad to C1 (same as kick),
which btw didn't cause the Tom to trigger when triggering the kick - but I'll start a new thread for that after I've finished investigating this one further
