There appears to be a quality of life bug when exporting PDF schematics.
When exporting a schematic to PDF format, I follow the following route: Document > Export > PDF... > √ Export.
**The document needs to** then **be manually identified as a PDF by adding ".pdf" to the text bar**. This does not automatically happen as with most programs. The dropdown menu does not give the save file type as pdf option either. Furthermore if you just rush through and hit "save", you will get a document with properties, file type: file.
Brand new interactions and interfaces. 
Easy to use and quick to get started.
