I just checked and it shows up for me. I would try closing your browser and trying again.

Yesterday a bunch of runners had this issue as well.

same problem today for me, missing category.

yeah if you set the category it doesn't actually set anything. been going on with a few games on my end

im just using resident evil 3: nemesis category

Twitch messed up a TON of game categories and box arts recently. I'm pretty sure Resident Evil 3 not showing up is a result of this. I suggest streaming under Resident Evil 3: Nemesis for now until it's resolved.
