get_field_object within loop

Setup: I have two templates and use the Genesis Framework hooks to populate them:

• event-template.php: displays all items of CPT ‘event’ (using a loop)
• single-event-template.php: displays a single event

The event-page uses ACF fields, among which a select field.
When calling get_field_object on the single-event-template the values display correctly. When I call get_field_object on the event-template (i.e. within the loop), no values are returned.
Note that get_field correctly returns the value of another field in both situations.

Code on both pages:

$eventTypeObject    = get_field_object( 'event_type' );
	$eventTypeValueArr  = $eventTypeObject['value'];
	$eventTypeValue     = $eventTypeValueArr[ 'value' ];
	$eventTypeLabel     = $eventTypeValueArr[ 'label' ];
	$custom_event_type  = get_field( 'custom_event_type' );

	?>
    <ul>
        <li>get_field_object: <?php echo print_r($eventTypeObject) ?></li>
        <li>field_object['value']: <?php echo print_r($eventTypeValueArr) ?></li>
        <li>field_object['value']['value']: "<?php echo $eventTypeValue ?>"</li>
        <li>field_object['value']['label']: "<?php echo $eventTypeLabel ?>"</li>
        <li>get_field('custom_event_type'): "<?php echo $custom_event_type ?>"</li>
    </ul>

	<?php

Output on single-event.php:

get_field_object: Array ( [ID] => 130 [key] => field_5b2a622f49bdc [label] => Soort event [name] => event_type [prefix] => acf [type] => select [value] => Array ( [value] => workshop [label] => Workshop ) [menu_order] => 4 [instructions] => [required] => 0 [id] => [class] => [conditional_logic] => 0 [parent] => 82 [wrapper] => Array ( [width] => [class] => [id] => ) [_name] => event_type [_prepare] => 0 [_valid] => 1 [choices] => Array ( [course] => Cursus [lecture] => Lezing [masterclass] => Masterclass [workshop] => Workshop [custom] => Anders ) [default_value] => Array ( ) [allow_null] => 0 [multiple] => 0 [ui] => 0 [ajax] => 0 [return_format] => array [placeholder] => ) 1
field_object['value']: Array ( [value] => workshop [label] => Workshop ) 1
field_object['value']['value']: "workshop"
field_object['value']['label']: "Workshop"
get_field('custom_event_type'): "Dit is een meesterklas"

field_object['value']: Array ( [value] => workshop [label] => Workshop ) 1
field_object['value']['value']: "workshop"
field_object['value']['label']: "Workshop"
get_field('custom_event_type'): "Dit is een meesterklas"
 

Output on event-template.php:

get_field_object: 1
field_object['value']: 1
field_object['value']['value']: ""
field_object['value']['label']: ""
get_field('custom_event_type'): "Dit is een meesterklas"

Question: why are the values not returned on the event-template.php page?
