[SEARCH & DISCOVERY] Complementary product not showing up when stock is 0

[sebashobo]

Hi all!

Recently i have found out that whenever a complementary product is sold out, it doesn't show up anymore at the linked product. 

This is not something we want, because we sell a lot of co-ord sets and we want our customers to always see this so that they can also sign up for the restock alert. 

Is there anyone who may know how to fix this? I tried to find a solution but couldn't really find anything.

Example: Product https://most-wanted.com/products/lace-up-jeans-light-blue is a matching set with https://most-wanted.com/products/lace-up-jacket-light-blue. Everything is set up as it should, but because the stock is 0 it doesn't show up at the pants.

Thank you in advance!
