Why when you add an embed link as a material item you can't edit the details

Why when you add an embed link as a material item you can't edit the details

If I choose to add a Vimeo video to be played in my lesson as a Material item, it seems that I am unable to edit the values set. In fact, you can't even see what they are to confirm exactly which video is loaded.

Have I missed something?

Why would we not be able to view and edit the material item added as an embed link?
