My out-of-stock products not displaying on my collections page properly.

I use the motion theme, I try other themes, ‘sold out’ products can be displayed on my collections page normally. 

Can anyone tell me what to do to show the products with 0 inventory？

This is the Motion theme I currently use, and the colection page does not display sold out products.

This is the collection page for other themes:

Where is the problem? How do i do it?
