I cant use a custom equalizer setting. how do i fix it?

[AC Question]

Whenever im playing music and want to change the equalizer settings, it only lets me choose the preset options, but i can't choose tr custom option because it doesn't appear. It's in the default equalizer.

Hello. Welcome to Android Central.

Which device are you using?

Samsung's Music app has an equaliser setting on my Note 3, as well as presets.
