How to delete the custom LAYOUT?

I duplicated the layout for test, but how can I delete them?

(cs-cart 4.0.1)

I find a delete icon under the “edit layout” page.

Thanks for posting! Wow, they sure made this one hard to find.

Select the layout then select the gear icon in tab. Look for trash can icon in lower left of pop up screen.
