I can’t make shorts anymore on mobile off my own videos

My most recent uploads do not allow me to make the shorts via the remix features like I have done in the past. I would rather not have to use CapCut on my phone or make the shorts in a video editor on my PC. It doesn’t have the remix button anymore. No copyright claims or etc and I do have audio and video remixing enabled in the settings. Anything I can do? Anyone else having this problem?
