Can't see Apache modules

Hi!
I’ve just installed Cent os on my server and the latest Webmin and I’m trying to configure them now. On the Apache configuration page, I don’t see the option to enable/disable the modules. I know is should be there because before I had ubuntu and I accessed it from there. I’ve attached a picture with what I see at server:10000/apache/index.cgi
Any suggestion is appreciated.
Thank you!
