How many different edits are there of Stevie Wonder’s “Music Of My Mind” album?

I have the original 1972 UK LP on Tamla Motown and I have the 2000 CD re-issue on US Tamla. Both of these have the same track starts and ends.

I also have, however, a Dutch “Milestones” double LP re-issue of “Talking Book” and “Music Of My Mind” in a gatefold sleeve. I’m not certain of its vintage, but the label is the late 70s blue Motown label as used in Europe, while the sleeve uses the Tamla Motown name and logo everywhere.

The version of “Music Of My Mind” found here has, for instance, an extra little synth run between “Superwoman” and “I Love Every Little Thing About You”. You can clearly hear the familiar end of “Superwoman”. Then there is a slight gap. Then this little synth run is heard. Then there is another slight gap, and then “I Love…” starts as per the “normal” release.

Any ideas?
