Hello,
I hope you are well.
You have to remove the template tags in page template to hide those.
As you are using free version you can’t edit templates tag directly.
In the free
You just need to follow this:
1. Copy page-templates directory from /plugins/download-manager/src/package/views directory to your active theme directory.
2. Make a new directory as download-manager in your active theme directory.
3. Now remove all files from {active-theme}/download-manager/page-templates except the template files you need to update.
4. Update template file(s) in {active-theme}/download-manager/page-templates directory as per your need.
Thanks
