Can't see apache modules in Webmin

[RobotFX]

I've just installed Cent OS 5 on my server and I'm trying to configure it using Webmin. Now I've reached the Apache section and I want to install/uninstall apache modules, but in the apache configuration page cannot see the modules section.
This is very strange. Previously I had Ubuntu and the modules link was there (pic) allowing me to access a page where I could easely enable-disable all the modules I wanted. Now is not :)
How can I fix this?
Thank you!

Have you changed the config to reflect where your CentOS apache files are? Make sure all the config info is updated and you can stop and start apache from within Webmin.

I think everything is fine with the config file, however have noticed something else which makes me more confused.
In the Apache config module, from within Webmin.Apache, these's an option to Always detect Apache modules automatically?. So, it was Yes before and I've set it to No. Now I can see the option to browse to the modules (see pic) but the changes I try to make there (enable/disable) don't save.
So not much of a progress :(

Also confusing for a noob: the Apache modules listed and enabled in the picture above don't match those enabled/disabled in the httpd.conf file. Here's what I have there:
