Why does Club Member Report get named with a date range?

Nowhere in the filtering or anywhere on screen am I giving it any kind of date range, yet when I run “Club Members”, it names the file with a date range. If all I’m looking for are active members (now, not previously or in the future), I can just ignore the date range part right?

I also just noticed this. I’m doing the qualification date club report and I got a name like this:

club-members-by-qualification-date-22406-from-2017-Feb-01-to-2017-Mar-31-on-2017-Aug-10

My qual. date was August 28. Threw me for a loop. (@Brent)
