This is a package extension. Some of the extensions it contains are not installed on your site.
Package extensions are a special extension type. They contain no code. Instead, they contain a packing list of other extensions (components, modules, plugins, templates, libraries, files) to install on your site.
If you are not a very experienced Joomla! user you are most likely conflating “component” with “package”. For example, our backup software Akeeba Backup is a package, not just a component. The Akeeba Backup component, by itself, cannot take backups before you update your site, provide a Joomla! API integration, Joomla! CLI commands to take and manage backups, integrate with Joomla! Scheduled Tasks, or integrate with the Joomla! User Action Log. These features are implemented by the plugins included in the package. Likewise, e-commerce extensions are packages. If you use just their component without their plugins you won't have any integration with payment and shipping methods, or you might be missing features such as product traits, or even being able to display the shopping cart!
These extensions are meant to work in tandem. If one or more of these extensions is missing the package may not work at all.
Moreover, future updates may fail because the developer (not incorretly!) assumes that if you are updating their software, their software must be already fully installed.
You will need to reinstall the package extension to make sure the missing extensions are installed back into your site.
It is recommended that you install the package which contains the extension twice in a row, without uninstalling it before or in between.
You usually end up in this situation if you uninstall an extension belonging to a package instead of simply disabling it, or by deleting / renaming the folder of an extension belonging to the package (a very bad practice that used to be recommended in the past for temporarily disabling plugins and modules preventing access to your site).
