The person who submitted it most likely doesn’t have access to that category. I’d recommend messaging @Bug-Support and they can format it correctly for you.
It’s not a major bug, don’t fret - the image you uploaded will still be the one that displays across the site and in all places other than on that tiny icon.
Apparently people are now allowed to post non-forum bugs in #forum-help:forum-bugs, which on top of that aren’t even required to follow the proper bug report format.
I encourage submitting all bug reports under #forum-help:forum-bugs now, as a moderator has decided that this sort of activity is perfectly allowed.
