Duplicate products in backend - Prestashop 1.7.5.1

[HenrikStrange]

I'm seeing multiple products with the same ID in the backend after upgradeing from 1.6.22 to 1.7.51.

In 1.6 i added this fix (solution from here) to AdminProductsController.php by replacing this:

        $this->_use_found_rows = false;
        $this->_group = '';

with this:

        $this->_use_found_rows = true; 
        $this->_group = 'GROUP BY '.$alias.'.id_product';

In 1.7 these two lines no longer exists, so I wonder if theres another way to fix the duplicate issue?
