Asset Browse Report Capped at 100?

I ran audit reports across several communities for the Asset Browsed activity. I noticed that several communities came back with a result of exactly 100 which seemed suspicious. So, I went into one of those communities and browsed six different assets then logged out, waited ten minutes and logged back in again.

When I ran the same report, I got the same value of 100 browses.

Is this a bug or do I have to tell it to report all browses somehow?

I was running the report for a one week period.

Thanks,
