Was not sure if the difficulty meant trophies, so this is a reupload of the run just in case, since my account has over 10k trophies. (Cheesy1's does not though)

I have just recorded what I think is a pretty quick duo showdown match, but when i go to submit it in the match victory category, every gamemode comes up except for solo and duo showdown. Is there a different category I’m missing to submit this in? or is this not a category?
