I don't know if this is the right place to report this. It's not really a bug but just a translation issue. On the spanish language Fairphone Privacy Impact setting labels for app notifications are wrong. For the Off setting it reads "Encendido", for the On setting it shows "Apagado", it's translated the other way around, and that confused me a bit...
Right translation is:
On -> Encendido
Off -> Apagado
I'm running Fairphone Open 16.07.1 but I think it the same applies for Fairphone OS 1.5.1
