I thought 1,3,5 in b flat major are b flat, d and e. I'm very confused that at 6:58 Tomo played E flat. Why is that?
Tomo is playing a I IV V progression in major triads: Bb Eb F.

Not sure this helps, but going through the same lesson.
Your original comment might be wrong?
I have notes in Bb Major:
Bb C D Eb F G A Bb
Chord Progression
I IV V
Bb Eb F
