Blur with icon

I have upgraded to pro to be able to show out-of-stock items as blurred with a cross.

I have set the default out-of-stock setting to “blur with icon” for all (Button, Color and Icon). However all of them has the same behaviour as when “blur” is selected .There is no difference between the “blur with icon” and “blur ” setting. Both settings result in just a blur.

I would like the sold out variant to be both blurred AND crossed.

How should i configure the “blur with icon” to see a different behaviour than “blur”?

I cannot find any documentation about this. Can you help?

Thanks!
