It sounds as if you expected a COUNT for each data point; but that's not what you asked for. Multiple points in the same location appear as a single point, just as you should expect.

Here you see the points (as you already plotted them) AND a count for each one:

DisplayTogether[ListPlot[swk, PlotJoined -> True,
     PlotStyle -> Hue[.9], Axes -> True, PlotLabel -> "
     Steigungswinkel", PlotRange -> All], Graphics[Text @@@ Frequencies@swk]]
