I can see why displaying an item instock would be needed to trick google and bait customers into visiting your site, but the website is clearly wrong and misleading by displaying the words instock when its not instock, its a "pre order". its the same principle of displaying an item at £10 then when you get to check out and it is now £20. Just put up a the correct wording "Available To Preorder Due 01/06/22"
