Why won't my videos turn into YouTube shorts?

I use the 9:16 ratio setting and the video is 2 minutes and 57 seconds long, which is under 3 minutes. These are two things that are needed to make a video into a short on YouTube. And yet for some reason, my video won't upload as a short. Can someone please just help me with this?
