plupload_image only working for first instance in functions.php file

I am using the latest metabox

Meta Box - Version 5.6.2
Meta Box AIO - Version 1.15.8
Meta Box Group - Version 1.3.13

In my functions.php file (in use for many years now) I have this recurring code (excerpt):

// META BOXES - PERSON META

add_filter( 'rwmb_meta_boxes', 'person_stuff_meta_boxes' );
function person_stuff_meta_boxes( $meta_boxes ) {

$prefix = 'person_stuff_';

$meta_boxes[] = array(
'id' => 'personData',
'title' => __( 'Person Data', 'person_stuff_' ),
'post_types' => array( 'post', 'page' ),
'context' => 'normal',
'priority' => 'high',
'autosave' => true,

'fields' => array(
// Full Name
array(
'name' => __( 'Full Name with suffixes', 'person_stuff_' ),
'id' => "{$prefix}FullName",
'type' => 'text',
'placeholder' => __( 'John Smith, SM \'84, PhD \'94', 'person_stuff_' ),
),
// Profile pic
array(
'name' => __( 'Profile photo', 'person_stuff_' ),
'id' => "{$prefix}profilePhoto",
'type' => 'plupload_image',
'max_file_uploads' => 1,
),
array(
'type' => 'divider',
),

// Company Logo
array(
'name' => __( 'Company Logo', 'person_stuff_' ),
'id' => "{$prefix}companyImage",
'type' => 'plupload_image',
'max_file_uploads' => 1,
),

Until recently, each instance of plupload_image allowed for an upload field to appear where we could upload an image...one for the person, another for a company logo, etc.

Now, only the first instance of plupload_image works. So in this case, the company logo field only gets the label but no field into which to dump an image.

Here are two screenshots...show how if you reverse the Company Name and Profile Photo, only the first gets the opportunity to upload.

I have rolled back WP to 5.7.6 and PHP and moved hosting services to test this, but no luck.

Any suggestions?
