How to make filter counts match distinct values

I went ahead and created a sample.  Here's a link to the PBIX.  You'll notice that there are a total of 10 visits, but that some of those visits have multiple report categories.  These reflect correctly on the pie chart and table - the pie chart is correct because I use a measure to DISTINCTCOUNT the VisitID.  However, if you look at the Filters, you can see the problem.  The Report Categories are correct, because if you select them, you get that number of items in the pie chart.  However, you'll see that the Market Segment filters are incorrect - for example, it says that there are 55 Digital Marketing visits, but if you filter by that value, you get 7 results (which is correct).
