Remove Categories from Buddypress Scholar Theme Nav Bar

Hello-

I am trying to remove the categories tab from the navigational bar in the Buddypress scholar theme. It seems as though the theme is not compatible with the menus function in the wp-admin section. I also tried to remove the code I thought was pulling this into the navigation bar in the header.php file, but had no success. Can you help guide me to this, or even make the them compatible with the menus function?

Thanks in advance.

Regards,

Jim
