awstats module is corrupted? there aren't all the folders and files

I tested to install awstats module but not work

the msg of module installed is this
The following modules have been successfully installed and added to your access control list :
AWStats Logfile Analyzer in /usr/libexec/webmin/awstats (264 kB) under category System

already this is strange because in another server (but not remember how installed) awstats work and the folder awstats is under usr/share (in the forum I see that also other user have in this path)

other strange is that the link is so
webmin>system>AWStats Logfile Analyzer

while in the server where work is so
webmin>servers>AWstats Reporting

other defference is that
in the server where work under
there are the folders
and not files (the files are all inner the folders, but not directly under awstats)

while in the /usr/libexec/webmin/awstats
there are only this folders
and some files see attached images;
how there isn’t the wwroot folder also there isn’t one file

obiovsly when clcik on AWStats Logfile Analyzer the msg error is
The logfile analysis command /usr/local/awstats/wwwroot/cgi-bin/ was not found on your system. Maybe AWStats is not installed, or your module configuration is incorrect.

errors I or module mistake?
