Products Imported into Shop Not Showing on Front End Until Saved

I have a product Importer that is almost working:

$API      = new PerchAPI(1.0, 'my_importer');
        $Importer = $API->get('PerchShopProductImporter');

        //Open the file.
        $fileHandle = fopen("/pathto/testData.csv", "r");


        while (($row = fgetcsv($fileHandle, 0, ",")) !== FALSE) {

            try {
                $Importer->add_item([
                    'sku'               => $row[0],
                    'title'             => $row[1],
                    'slug'              => $row[2],
                    'description'       => $row[3],
                    'status'            => true,
                    'brand'             => 1,
                    'catalog_only'      => false,
                    'price'             => ['gbp' => 10, 'eur'=>12, 'usd'=>13],
                    'sale_price'        => ['gbp' => 8,  'eur'=>10, 'usd'=>11],
                    'trade_price'       => ['gbp' => 7,  'eur'=>9,  'usd'=>10],
                    'on_sale'           => false,
                    'tax_group'         => 1,
                    'stock_status'      => '1',
                    'stock_level'       => '199',
                    'stock_location'    => true,
                    'max_in_cart'       => 10,
                    'requires_shipping' => true,
                    'weight'            => 100,
                    'width'             => 20,
                    'height'            => 15,
                    'depth'             => 30,
                    'productStatus'     => 1,

                ]);    
            } catch (Exception $e) {
                die('Error: '.$e->getMessage());
            }

        }

Currently I'm only testing, so I'm only importing the first 4 rows of data, and hard coding the remainder. Debug shows the results as follows:

The script works fine and the product appear in the admin area. However until I open a product and save it it doesn't appear on the front end? When I open the product the status is showing as 'Active', however until I save the product it doesn't appear on the front end of the site.

Can anyone help?

I'm not 100% on what this script does but It appears the product data is being inserted into the 'perch3_shop_products' table, but the 'perch3_shop_index' table isn't updated until I save the product through the product editor admin screen.
