Do you actually have a user named "27"?

I'm thinking this is an instance of a privilege for a user who used
to have sysid 27 but has been removed.  The privilege entry is still
there, but is listed with the numeric sysid because the system cannot
find a name to display for it.

You can ignore the privilege item since it's nonfunctional (can't
ever be used).  Or you can create a user with sysid 27 (read the
CREATE USER man page), then REVOKE using that username, and
finally drop the user again.
