Custom design Quick Checkout page

Custom design Quick Checkout page

Our checkout page with this addon opens at "{our-domain.name}/qcheckout?check_login=1". And this page has the home page design: home page modules are displayed, page has home page body classes, etc.
In other words, it visually looks like the checkout form is displayed at the home page.
We have a menu item for the standard JoomShopping checkout page. Before installing the addon, the checkout page opened correctly (it has a special custom design), not looking like the home page.
It looks like the addon is ignoring this menu item.
How can we create a checkout page with our own design?

Thank you so much.
In the email I received after purchasing the addon, the latest version was 2.3.15, just like the addon's description on the website.
Installed version 2.3.16. The Quick Checkout menu item type has appeared. The page is working correctly now.
