How show members only in multiple categories

solved by myself…
replace in class-woothemes-our-team.php as follow

// Setup the taxonomy query.
if ( ” != $tax_field_type ) {
$term = $args[‘category’];
if ( is_string( $term ) ) { $term = esc_html( $term ); } else { $term = intval( $term ); }
$term = explode(‘,’, $args[‘category’]);
$query_args[‘tax_query’] = array( array( ‘taxonomy’ => ‘team-member-category’, ‘field’ => $tax_field_type, ‘terms’ => $term, ‘operator’ => ‘AND’ ) );
}
