I want only one network as an option

Despite selecting Electrify America as a strong favorite, not only do I NOT get Electrify America, I get dozens of networks I've never heard of and I do not want to use different apps and payment systems for them. Going in and marking them as avoid only gives me a new set of stations I don't want. Sometimes the same ones keep coming back even marking them. I'm going to have to give up using this app for this trip.
