Automatic Upgrade – No FTPS option shown

Hey, so I have a new wordpress install and want to upgrade a plugin automatically. I suppose because the ftp user is different, it’s asking for ftp info. I can only connect using an FTPS connection, and I know wordpress supports this, but in my case, there is only a radio button for FTP! The FTPS radio button simply doesn’t show up on the page where it asks for FTP info!

Any ideas why it would be missing?
