In As and AI the presence of these bars does not result from the notation – the Waltz ends in bar 128. In A bars 129-152 are not written out with notes, but only marked in an abbreviated manner (with subsequent letters) as a repetition of bars 1-24. At the same time, Chopin overlooked the 'N' letter, corresponding to bar 13 (141); this patent mistake either did not confuse the engraver of FE (→GE,EE) or it was cleverly corrected.
