products not showing up on confirmation page

I am having a problem with the thank you page. I purchased it via envato

First, the billing name is not showing up, but it is only showing the actual snippet code.

Second, the products are not showing up correctly.

You can see the issue on this screenshot: https://captainmanicorn.com/wp-content/uploads/2021/06/Screen-Shot-2021-06-02-at-3.44.06-PM.png
