Schumann Piano Concerto In A Minor (Score Discrepancies)

[louispodesta]

I have the Schirmer, Peters, and Music Minus One scores of the Schumann Piano Concerto in A Minor.  Measures #24, 25, 28 and 29 are different in the Schirmer, than in the other mentioned editions.  The notes in both hands in the second and third beats of each of these measures are not the same between the two versions

Further, the Piano Street library agrees with the Schirmer.

I would very much like your input on this if you have run into this problem.
