Visual based on Calculated Table not responding to Slicer Filter

Hello,

I have a data set that looks like this (simplified):

I need to count the occurences, so I created a table:  SUMMARIZE('DataSet','DataSet'[Step])

Then I created a bidrectional relationship between 'Table' and 'Dataset' using [Step]. 

Then I added a new calculated column to 'Table':  CALCULATE(COUNTA('Dataset'[Step]),allexcept('Table','Table'[Step]))

The reason why I am using a caculated table is because I need a cumulative count of the strings.  I have a third column which uses the EARLIER function to achieve this. 

All of this works fine.  The problem occurs when I put the results into a visual on my report, the visual does not respond to any filters or other visuals.  These filters and visuals are all based on 'Dataset', and THEY do respond to the visual when I click on each string count...  it just doesn't work the other way around.

I suspect this is due to the ALLEXCEPT function ignoring any applied filters.  So I used FILTER('DataSet','DataSet'[Step]='Table'[Step]) instead, and it still doesn't respond to my filters.

For example, if I elect to filter by USA, the visual does not respond.  However, if I click on the Step 1 count, all the other visuals DO respond.
