Can't download separate parts after transposing
I'm looking to download the score linked below with separate parts (violin 1, violin 2 etc.), but also after transposing. The website does not allow me to transpose, only the app does. When I head on to the app, I can transpose, but not download separate parts. When I use the desktop app, I have to first import the PDF, then transpose. However, the import changes the notes, key signature, time signature, and even staves in some parts. Obviously this is a pretty flawed approach.
Does anybody know how I can get the following score in separate parts, and transposed up two semitones (it was in D major, and I'd like it in E major)? It would be incredibly helpful. I have also attached a downloaded version of the full score in E major if this is helpful, but was unable to download separate parts.
