Postfix Mail Server module stuck in 'Un-used Modules'

I am running Centos 5, Postfix 2.3, and Webmin 1.510.

My Postfix Mail Server module is stuck in Un-used Modules. Postfix seems to run fine. If I use the webmin search for the module, it will show me the config page and everything seems to work.

I have tried uninstalling the postfix module and reinstalling. That did not solve the problem.

Can anyone give me any clues on how to troubleshoot or fix this please?

After clicking Webmin, look on the very bottom of the left-hand nav bar, you’ll see an option named “Refresh Modules”. Does Postfix move to the Servers area after refreshing the modules?
