Custom attributes and swatch profile

Hello,

In a product made with WooCommerce Bundle (which uses variations) I can’t hide the thumbnails of the products that are out of stock. I have succeeded once, modify some additional settings (display from horizontal to vertical) and from then on I have not been able to get it back.
What are the correct settings please for an attribute and category custom so that only in that combination it hides the products? I have generated a swatch profile just for this called “DMTK Vest”.
Many thanks and best regards.
