Symbol of "Previous Track" becomes "Genius Shuffle"

Hi,

I believe I had accidentally clicked some buttons on my keyboard when I was sleeping.

I found out that the Previous button on my Music app had become the symbol of Genius Shuffle.

I like Genius, but still, I want my previous button back due to convenience😂

I tried to look for different topics but could not find any solutions, so I came here for help.

Thanks.
