visual level filter

Hi Team,

I have stacked bar graph visual in which am displaying visits count where i've Mon-Year (Jan-2016) as x-axis. Both Mon-Year and VisitsCount are under visual level filters.

Now the issue is: If i select one Mon-Year as filter and also select a value like VisitsCount is less than 500, am not getting the correct results. in the sense, if i have 2 values less than 500 am getting only 1 value!!

Any ideas on such behavior??

Thanks in advance,

Swaroop
