Removal of Menu:owner_block

Hi, first i thought it could be a theme issue, but i now believe it's a core relates issue. I am looking to remove the owner:menu_block from my elgg 1.9.2 install. It isnt in theme and the theme creator ( Per Jensen of Aalborg theme) told me it's core related. So could anyone please help me to remove the menu:owner block from my install? The user icon / avatar and link on right hand side. I would prefer to use the block provided by 3c river. All help is appreciated. thank you :)
