You need to specify the run type even if you use the submit button on that categories page :)

Back in the day all files was what I considered 100% runs, this was just strictly for myself back in the aughts when I was speed-running before I was aware of any regulated online communities outside of posting something on youtube lol. But even as an unofficial category try running an all files run sometime, its pretty fun especially in the psx titles and REmake, totally scrambles the run.
