Hello,

This issue is related to the layout builder that you used on your cart page because the plugin uses special hooks to show buttons that are not present on the default page builder cart layout. Two different approaches can fix it:
1. Disable the layout builder on your checkout page.

Or

Add the “woocommerce_after_cart_table” in another on cart page (https://monosnap.com/file/6ExOsXPkMtDoXAw4OjgYf7VN2fs3jb)

Here is a tutorial that should help you https://xtemos.com/docs-topic/custom-hooks-and-plugins-compatibility/
