b. 90-91

2 slurs in A1, literal reading

Continuous slur in FE (→EE)

2 slurs in GE

..

In A1 both the ending of the L.H. slur in b. 90 and the starting point of the slur in b. 91 are probably inaccurate, which is indicated by a comparison with GE and analogous b. 94 and 99 in the very A1. The engraver of FE, misled by the slur in b. 90, combined both slurs in one, which does not result from the notation of A1 and certainly does not correspond to Chopin's intention. This erroneous version was repeated in EE.

 on 3rd beat in FE (→EE)

 on first beat in GE2

..

 under the 2nd quaver is both in A1 and GE1, which proves that it is not an inaccuracy, but a precise indication on how to preserve the G1 bass note with a pure G major chord. In the remaining sources, the mark was moved due to carelessness or due to an attempt at correcting the allegedly inaccurate notation of A1: in FE (→EE) it was moved under the 3rd beat of the bar, whereas in GE2 to the beginning of the bar.
