Duplicated entries when set multipe selection in filter

Hi Anonymous ,

Thanks for your quick reply.

Simply saying, I have 2 columns (Internal Severity/External Severity) in table A with same value ranges (Low, Medium, High, Critical). I created another table B with the same values as a filter (SeverityValue). I want to show the measurements related to these 2 columns in one visualization with the second table B SeverityValue as a page filter. 

In the measurement 1, I use:

When I choose a single value from filter B SeverityValue, the table format visualization shows the correct selected values. But if I choose multiple values from filter SeverityValue, the table visualization will show each entry "mutiple" times. 

I wondered whether it is because there is no directly relationship between B SeverityValue and Table A. Do we have anyway to show only desired entries (without multiples) when choosing muitple values from SeverityValue.
