Out of stock products displayed like an empty space

Hello,

I have a problem with the out of stock products.
In WooCommerce/Products/Inventory – I checked hide out of stock products.

If you go on a category page
https://librariaromanilor.com/categorie/carti/literatura-romana/

you can see that every out of stock products is displayed like an empty place. Sometime, the page will display 3 products, sometime 2 or sometime 6. This is very, very annoying for the clients.

Can you, please, give me a solution for that?

Thank you,
