Download Vector instead of jpeg

My husband downloaded a jpeg version of a file he wanted for a project. I need the same file in vector form. The only option I'm getting is to redownload. The rest of the files in this series all come as both vector and jpeg, so I have a hard to believing this one doesn't have both as an option. My default settings are set to always ask which type I want to download, but it's not doing that. There is also no setting icon like I've seen in screenshots given in responses to similar questions. How can I get it to let me download the vector form?
