Hi Pankaj,
Thanks for the quick response.
I'm currently working on getting the website up, but in the meantime I was able to recreate the bug in a completely fresh install of the Mason template, repeatable in Safari and Chrome.
In the fresh install I created a new root level menu and assigned it to a single article which I created through the menu's create article interface. In the article I clicked the add module button and added the existing "client." module into the otherwise blank article.
I also set the "clients." module to display on all pages.
As I described, the module is there, but nothing other than the title is actually visible. However, the same module which has been set to be visible on all pages is visible below the article. The attached screenshot shows what I'm seeing.
