Output Module Not Working - Limited Options

After upgrading to After Effects CC I am facing problems when using output modules in the render queue.

I can use one of my Output Module presets as a starting point but when I try to change the settings, it only shows a limited number of options. For example, If I choose a H.264 preset and try to adjust the settings, it changes to show me the options for an AVI and the dropdown list only shows a limited range of options. (see below image)

This is annoying, I can't even change the data rate or audio options of a preset.

Has anyone else experienced this issue?

Thanks
