I have added a Module Class Suffix to a BT Login module but it is not being output in the code in most of the module positions. I have placed a standard Joomla search module in the same positions and the Module Class Suffix is output in this case.

I am using the T3 framework blank bootstrap template. I have tried many positions but the only location the Module Class Suffix is output is in the footer positions. These are the other positions I have tried where the Module Class Suffix is not output: languageswitcherload, head-search, home-1, home-2, home-3

Am I missing something somewhere?

Many Thanks!
