    So to use Jaccard Similiarity with K-nn, you have to set the "Measure Types" parameter to Nominmal Measures. Then you can select Jaccard Similarity for the nominal measure.

    you need to make sure that your input data is all nominal, not mixed with numerical values. You can use the Numerical to Nominal to do this.
