I'm working through Mark Levine's Jazz Theory book... at the start of Chapter 2 (page 15 first example) where he introduces the ii-V7-I progression in Eb major, he writes a progression that goes

EbM7 used in the progression outlined above contains an
F nat instead of a
Wouldn't it be a Eb-add9 chord and not a Eb7 if you use an F natural instead of the D natural?
The notes are:
Coming from a tonal theory background, I am genuinely confused at why jazz musicians consider a Eb-add9 the same as a EbM7?
