Stock Availability does not changing after import CSV

Hello,

When i import or update the products from a csv file all working fine but the Stock availability does not changing as it should be. I importing also the stock amount and managing stock == yes.
I look over this support forum and i found similar case so i updated to the last version (1.5.4) and tried the following code in functions.php

add_action(‘wf_refresh_after_product_import’,’refresh_after_product_import’,1);
function refresh_after_product_import($product_object) { $product_object->save(); }

With this code in my php file the import does never begins. It is not working.

If i enter in one of the updated – imported product and just click manual the update button, the stock availability text is correctly changing, i mu st found a way to do this update to all imported products at once with a background task, can you please help me to find a working solution? Thank you.
