Numinix Product Fields w/ 1.5.8a Not Working

[OldNGrey]

I have it working on zc158 in production and zc158a in test and I see that I have created a lang.numinix_product_fields.php file in includes/languages/english/extra_definitions
The contents of file is the old language file updated for zc158. The new main contents are:

<?php
$define = [    'TEXT_PRODUCTS_ACTUAL_WEIGHT' => 'Products Weight: ', 
    'TEXT_PRODUCT_DIMENSIONS' => 'Dimensions: ', 
    'TEXT_PRODUCTS_LENGTH' => '', 
    'TEXT_PRODUCTS_WIDTH' => '', 
    'TEXT_PRODUCTS_HEIGHT' => '', 
    'TEXT_PRODUCTS_DIAMETER' => 'Diameter: ', 
    'TEXT_PRODUCTS_CONDITION' => 'Condition: ', 
    'TEXT_PRODUCTS_UPC' => 'UPC: ', 
    'TEXT_PRODUCTS_ISBN' => 'ISBN: ', 
    'TEXT_PRODUCTS_OUT_OF_STOCK' => 'Out of Stock', 
    'TEXT_PRODUCTS_SKU' => 'SKU: ', 
    // CONSTANTS not defined
    'SHOW_PRODUCT_INFO_DIAMETER','', 
    'SHOW_PRODUCT_INFO_DIMENSIONS' => '', 
    'SHOW_PRODUCT_INFO_ACTUAL_WEIGHT' => '', 
    'SHOW_PRODUCT_INFO_CONDITION' => '', 
    'SHOW_PRODUCT_INFO_UPC' => '', 
    'SHOW_PRODUCT_INFO_ISBN' => '', 
    'SHOW_PRODUCT_INFO_OUT_OF_STOCK' => '', 
    'SHOW_PRODUCT_INFO_SKU' => '', 
    'SHOW_PRODUCT_INFO_CARE_INSTRUCTIONS' => '', 
    'SHOW_PRODUCT_INFO_DESCRIPTION2' => '', 
    'SHOW_PRODUCT_INFO_CONVERSIONS' => '', 
    'SHOW_PRODUCT_INFO_SMALLER_UNITS' => '', 
];
return $define;
