Question on Mendelssohn's op.82 variations in E-flat

[mostlyclassical]

Can anyone tell me, 4 bars before the final chord of the piece (count begins including the last one) is the last note in the left hand really an F, as in my Dover book which I don't trust much? May be it should it be A flat, it sounds softer-better, just like in the theme, at the very beginning? And 6 bars before the ending, could you describe the rythmic pattern? Have doubts here too. Anyone with a more authoritative edition? Thanks.

My version also has the F, wich sounds right to me.
The rythm is not hard at all, just try putting notes where there are pauses and clap or sing it. Then you will get 16-16-8-16-16-8, when you have this just remove the 2nd 16th note and you have it

It's not that I find it difficult to play, but for some reason I feel it should be 8-16th.pause-16-8-16th.pause-16 and was wondering maybe it was printed incorrectly... And still, I can't swallow that F unison.
