Revert to old link after a new link is created

A new link has got created from the file i am working on. Now i am not able to revert to the old link. I was been updating the prototype by clicking on ''update link" this morning. All of sudden, create link was showing and have no clue how it has changed. In share section, there are two options i.e., manage links and create new. When i clicked on manage links, it directs me to a page where list of files can be seen as shared in the attachment below. I then marked on the file i need to update, but nothing happens.

Is it possible to revert the prototype to the old link?

Thanks in advance for the consideration!
