How to Count total number of rows in table after using some filter. I have created column and Measure to calculate number of rows in table but could not get right result.

As you can see in pic 4th rows (Yellow Highlighted) has count value 2 insted 1. Total count of table should be 5 insted 6..  Please guide me how can i calculate the right count.
