{{heading_title}} is not right if we add another module in the layout. For example, if you add a Featured to Content Bottom to the Information/Contact, the heading_title in the Contact page will show as 'Featured' instead of 'Contact Us'.
I think somewhere the variable {{heading_title}} has been set to the last module name instead. However, I do not know how to correct this.
This also happens to any other page like Returns, Site Map, Shopping Cart as long as it shows the '<h1>{{ heading_title }}</h1>' in the same page.
You can have a look at my demo site from: http://demo.giftalot.com/opencart320
Thanks very much!
