[RMMV] MOG_MASTER_MV

Hi all I just downloaded MASTER DEMO MV by Mog and I'm kinda baffled how to change templates.
https://atelierrgss.wordpress.com/download-page-mv-01/

It comes with a folder called BattleHud_Templates and I want to use the one named 01_Classic I put all the files in their appropriate places and turned the Scripts on but there are no changes to the battle screen , so I have no idea what to do , if possible could anyone help me please , I'm pulling hair out trying to figure out what I'm doing wrong.

Any help would be greatly appreciated.
