Before everything else, make sure you are reading the documentation.

Can you provide more detail on the steps you have followed, and what you are trying to achieve. People often use terms like tracks and songs interchangeably, but in ST they are very specific and different things, so please ensure you are precise with terminology.
If you mean sorting songs in the songs list, then https://stagetraxx.com/docs/v4/library/songs/#sorting-songs
If you are creating a Playlist (how you would organise a group of songs for, say, a performance), and sorting songs in a Playlist, then https://stagetraxx.com/docs/v4/library/playlists/#sorting-playlists
Also, "the latest version" isn't a thing, always provide the actual version number. About 50% of people who post they were using "the latest version" are not, and it is discovered later.. all because people make assumptions 🙂
