Hi Beuza,
Can you please give this code a shot?

/**
 * Remove groups from user profile based on member type.
 */
function buddydev_remove_group_based_on_member_types() {
	if ( ! bp_is_user() ) {
		return;
	}

	$user_id = bp_displayed_user_id();

	if ( ! bp_has_member_type( $user_id, 'agent' ) ) {
		bp_core_remove_nav_item( 'groups' );
	}

}

add_action( 'bp_setup_nav', 'buddydev_remove_group_based_on_member_types', 1001 );

/**
 * Remove groups from adminbar based on member type.
 *
 * @param array $nav nav items.
 *
 * @return array
 */
function buddydev_filter_show_hide_groups_in_adminbar( $nav ) {
	if ( ! is_user_logged_in() ) {
		return $nav;
	}

	if ( ! bp_has_member_type( bp_loggedin_user_id(), 'agent' ) ) {
		$nav = array();
	}

	return $nav;
}

add_filter( 'bp_groups_admin_nav', 'buddydev_filter_show_hide_groups_in_adminbar' );

It works with our Member types pro and most probably will work with the other plugin too.

Please make sure to use “agent” like shown below in the member type name.
