Hi Ted. Yup, as Bachus said, I rarely visit this sub-forum of the site - so I've just seen your question.
On the i30, recognition modes are a bit different. There are just three:
Easy
Normal
One Finger
"Easy" results in Eaug
"Normal" results in C
"One Finger" results in C7
So I'm not really sure what the correlations are there.
I have a Pa3x and my result on those two notes is the same as yours, "E #5". I'd never come across this before as I'm always locked in Expert mode, not that I'm an expert :), but I do play full three- and four-note chords all the time in the left hand.
Hope this helps you out.
