I'm sorry for the trouble and confusion. The "save as PDF" option was discontinued several revisions ago as it was not supported by the Windows operating system. Assuming you are on a Windows computer, the only workaround is to find third party software that allows you to save as PDF from the print dialogue. If you are on a Mac, the PDF option is already included in the lower left corner of the print dialogue. We are currently working to find a more suitable solution for the next revision.
