Gil, I followed your tutorial (https://datachant.com/2018/02/07/book-excerpt-basic-text-analytics-powerbi-powerquery-excel/) . everything works until “Click on the filter icon of Topic column and select Remove Empty in the filter pane.” – essentially it looks like all my values in the Topic column returned null. Because when I filter on remove empty – essentially the whole table is filtered. Until then – everything followed according to your tutorial. I wonder what I am doing wrong? Any insight?
