Pre-order is shown on most Google search product page results

[DanGB]

Hi, I am having a strange issue.

On most Google search results of our Prestashop site product pages, it shows 'Pre-order' on the search results.

If you google:
Helix Single Mass Flywheel Performance Clutch Kit - AKS tuning

You will see it lists the price and Pre-order at the bottom of each relevant result.

It happens with most but not all products.

The site DOES NOT have any pre-orders and never has.

Ive searched the 'pre-order' text in all the site files and database and barely comes up and where it does its not relevant. I just cant work out where its coming from.

Prestashop 1.7.6.4.

Having the exact same problem and it is causing me sales!

Can anyone guide us to a solution please?

Ive found the solution. 😁

In ProductLazyArray.php:

public function getSeoAvailability()
    {
        $seoAvailability = 'https://schema.org/';
        if ($this->product['quantity'] > 0) {
            $seoAvailability .= 'InStock';
        } elseif ($this->product['quantity'] <= 0 && $this->product['allow_oosp']) {
           /* $seoAvailability .= 'PreOrder';*/
			 $seoAvailability .= 'InStock';
        } else {
            $seoAvailability .= 'OutOfStock';
        }

        return $seoAvailability;
    }

I changed the preOrder to InStock always.

I don't use stock management, hence why everything was 0 stock and set to pre-order.
