Hi,
In the current version of robinhood, fileclasses are only taken into
account when they are used in a policy.
The point is your fileclass didn't exist when robinhood processed the
entries (when scanning or reading changelogs)
so they do not appear in the fileclass report for now.
But don't worry, entries will be considered and updated when you run the
migration policy,
or the next time rebinhood processes them for any reason (scan or
changelogs).
Regards
Thomas
