I'm working on trying to find the fix for the "Save Webinar" button that displays below each individual webinar replay video. Metabox.io updated the Favorite Posts addon to version 2.0 and when that happened we lost all our text in the buttons. For now, simply clicking on the green "empty text" box will still save the webinar and you can then see your list of saved webinars here. https://wpstudio.com/video-library/saved-webinars/
