Wishlist not in stock error

Hi,
In my wishlist page I have a product who is out of stock but it’s mantioned as in stock.
You can see the wishlist page :

But for this specific product (“bleu canard”) you can see that it is nos available:
https://www2.maison-chateau-laguiole.fr/boutique/bleu-canard/

Could you help me to make it work properly?
