Unique returning visitors - reports for daily only

Hi. running piwik 1.9.2

I only get “unique returning visitors” stats for a daily report. Not monthly, weekly, or date range.

i have the flags set in in config.ini.php as follows.
enable_processing_unique_visitors_day = 1
enable_processing_unique_visitors_week = 1
enable_processing_unique_visitors_month = 1
enable_processing_unique_visitors_year = 0
enable_processing_unique_visitors_range = 1

per the comments in the global files, I have dropped the piwik_archive_* tables, and have rerun reports.

I could use some help troubleshooting this one.

bump. I would appreciate some guidance.

This is by design, we don’t process this stats for bigger periods (yet)

Thank you.
