Apple Music - Edit song durations

Hello,

I'm currently having issues editing the duration of a song I have in my Music Library. I've made it as for as editing it in the options tab for individual song through the Get Info option. After editing the stop times (with the little box checked off) the changes aren't applied and the song remains it original length.

I'm not sure if I'm doing anything wrong or just missing something.

My software is up tp date with it currently being macOS Catalina 10.15.3.

Thank you in advance
