No puedo desbloquear la pestaña hsl/color/blanco y negro

[Guest]

En la parte de revelado, la pestaña hsl/color/blanco y negro esta bloqueada o desactivada y no hay manera de activarla.

Estaría realmente agradecida si me pudieran dar una solución al problema.

Si sirve de ayuda la versión que tengo es 7.4 y mis fotografías son formato jpg.
