In addition to the comment from @Niyas, all Enterprise modules are covered by the "Odoo Enterprise Edition License v1.0".
What you are seeing in your screenshots is the "default" license because these modules happen to not have the metadata in the manifest specified.
If you look at the code, the comments in manifest do refer the reader back to the file specifying the license.
You can see this (that what you are looking at is a default value because none is specified) via https://github.com/odoo/odoo/blob/14.0/odoo/addons/base/models/ir_module.py#L295 - you could argue this is a bug that we need to fix - but the license is the one in the file distributed with the code that is referred to at the top of the manifest.
