Show out of stock swatches in configurable (Magento 2.2.6)

Question

I want to show out of stock product swatches in configure product. In the admin settings, Stores -> Configuration -> Catalog -> Inventory -> Display out of stock products, this is already set to "Yes" but not working.

For example, if i have 3 color in configure product and one of them is out of stock then it should be shown with red strike. But it only shows 2 color of swatches.

I install same version of magento and it's working fine when i set Display out of stock products to yes. Then why it's not working in my current project. Can anyone help me to solve this.
