Unique visitor for custom variable in a date range

Hi,

I am tracking two custom variables, Age and Gender. I am able to see the unique visitors count for a given date. But when I select a date range, the count is not showing up.
Is there any custom setting which need to be done at the php.ini file
I have enabled all the below settings

[General]
enable_processing_unique_visitors_day = 1
enable_processing_unique_visitors_week = 1
enable_processing_unique_visitors_month = 1
enable_processing_unique_visitors_year = 1
enable_processing_unique_visitors_range = 1

Hi Matt,

Any updates on this, can you please let me know if there are any custom settings required

Unique visitors count is only supported for days at this stage unfortunately.
