CMB Metabox Multiple taxonomy_select

<?php
// I hope this can help out someone else so they don't go though the same frustration that I did. I was trying to use the taxonomy_select
// metabox to display two dropdowns/select boxes but couldn't get them both to save. Saving or updating would force both to save as the
// second value. Below is the code that I used to allow me to save the data separately into usable post meta. If you are using this with
// multiple selects there is still no need to create more then one function, this will work on all of them.

// I first created a function outside the metabox to loop though my custom taxonomy.

function get_team_names( $taxonomy = 'team_category', $args = array() ) {

    $terms = get_terms('team_category', 'orderby=none&hide_empty');    
    // Initate an empty array
    $term_options = array();
    if ( ! empty( $terms ) ) {
        foreach ( $terms as $term ) {
            $term_options[ $term->term_id ] = $term->name;
        }
    }

    return $term_options;
}

add_action( 'cmb2_init', 'sports_ticker_custom_metaboxes' );

// Then when created the metaboxes I then pulled it into my metabox like this. This allows you to pull in a list of your taxonomies 
// very much like the taxonomy_select metabox but will save all values separately.

$ticker_data->add_field( array(
	    'name'    => 'Home Team',
	    'desc'    => 'Choose the home team.',
	    'id'      => $prefix . 'ticker_home_team',
	    'type'    => 'select',
	    'options' => get_team_names(),
	) );

// Lastly, below is the code needed to display the information on the front end.

global $post;
$home_team_select = get_post_meta( $post->ID, '_ticker_data_ticker_home_team', true );
$away_team_select = get_post_meta( $post->ID, '_ticker_data_ticker_away_team', true );
                                                
$home_name = get_term_by('id', $home_team_select, 'team_category');
$homeTeam =  $home_name->slug;

$away_name = get_term_by('id', $away_team_select, 'team_category');
$awayTeam =  $away_name->slug;

echo $homeTeam . ' vs ' . $awayTeam;
