Why does the title/numbers of my file change when exporting/sharing a PDF or PPT to another note-taking app?

Sorry if this seems like not a big deal, but it drives me nuts when I need to export 20+ PDF/ppt. files at a time, and keep having to manually change the name within the other app to keep my slides in order. I have Canvas on both my iPad and my iPhone and this issue happens in both apps. Hopefully the photo attached can explain better. Thanks in advance to anyone who can help.

Hello @AsaLiebowitz 

Are you exporting files or student submissions or grades? Generally speaking things that downloaded from Canvas aren't able to be renamed unfortunately. Can you give us any more description of what you're downloading and exporting?
