Is anyone elses long videos turning into shorts?

So i post music on my channel and the last few videos ive posted that are just songs i worked on (longer than 60s btw) they turn into shorts. The longest a youtube short can be is 60s but my videos can be about 2-3 minutes long but they still turn into shorts. I post my videos on mobile and there is an option to post a video, community post, or a short and i always tap the video button and it worked for a while but now even when i tap video it automatically turns my video into a short but it keeps its length so im post 2-3 minute shorts.

I made a new channel for my music and my songs i make on there are like only a minute but it doesnt get converted into a short its just a normal video.

if anyone can let me know whats wrong then please do 🙏
