Reference Supplier Problem (ps_product / ps_product_supplier)

[JoZu]

I have a little code for show reference code in product miniature and product page, this one:

{if $product->supplier_reference}
<p><strong>{l s='Supplier ref:' d='Shop.Warehousetheme'}</strong> <span>{$product.supplier_reference}</span></p>
{/if}

But supplier reference show only in some products i cant update this, ( i see database ps_product->supplier_reference and product page and all is ok.)

Search on internet show me this result:

https://github.com/PrestaShop/PrestaShop/issues/20094

There are 2 supplier refenrences in 2 ddbb tables (ps_product and ps_product_supplier)

Question:

How to show the ps_product_supplier -> product_supplier_reference for test?

Thanks so much!

PD: When edit product -> go to options -> i see reference supplier i push save button and reference show on product page and product miniature!
