Problem with GitHub converting .aup files to html

I am teaching a digital media class for the first time, and I have asked students to create an audio project and post their files to a GitHub repo. However, it seems that GutHub is converting those Audacity .aup files into html files. Is there a way to get aup and also mp3 files into the repo without them being converted into html?
