FreePBX not updating .conf files

I am currently running Asterisk 1.4.21.2. This is a new install. When I make updates via the FreePBX web interface I do not see them reflected in any of the .conf files. My questions are as follows:

  1. When I make a change in the FreePBX web interface (adding an extension for example) I would expect this change to show up in extensions_additional.conf. Is this a correct assumption?

  2. If so, what are possible causes for this file not to be updating?

Thanks in advance.

If anyone is having this same problem, what I am having to do is manually execute the retrieve_conf script to update my .conf files as follows:
