I'm using--ignore-crawlers (together with--unknowns-as-crawlers) for removing bots from the report, but in the "Operating Systems" section, goaccess reports in the UI multiple unknown crawlers.
There are no known crawlers.

I would have expected to see no crawler at all.

From the man page

       --ignore-crawlers              Ignore crawlers from being counted.       --unknowns-as-crawlers              Classify unknown OS and browsers as crawlers.

goaccess version:

GoAccess - 1.9.3.For more details visit: https://goaccess.io/Copyright (C) 2009-2024 by Gerardo OrellanaBuild configure arguments:  --enable-utf8  --enable-geoip=mmdb  --with-openssl

did I misunderstand the documentation, or is this a bug?

Is there a way to find out which entries are still recognized as crawler but not filtered out?
I could not find the information in the report generated with-o /tmp/report.csv
