New links in Sharepoint containing spaces include %2520

When I create new links on our Intranet Sharepoint page, if the target file has spaces in it then after the link is created the final result for something like File name becomes File%2520Name. Old links are still using the standard %20 method and work fine. These new links however, are broken. From what I read, %25 is a % so somewhere, Sharepoint is randomly seeing an additional one of those? My steps for adding a new link to a file are: Edit page > Insert > Link > From address. I put in the full file path and precede it with file:// and the end result is a file path with %2520. My only “fix” for this so far has been to rename files to remove the spaces. Any thoughts?
