This is not a question, but an illustration of how it might happen that 4 different fingerings would be added to a single voice. The two sets of fingering in italics are by the composer, who is showing alternate fingerings for first and second time through. The other fingering is editorial, since the original fingering might be problematic for some players.
I was able to do this by using the fingering popover for the italicized fingering and playing techniques for the non-italicized fingering both added to two unison voices, one of which is hidden.
