Pro Chime hidden networks

Hi, I have the pro chime, i'm not using the wifi extender function and this is off I the settings. however, there is both a 5Ghz and a 2.4Ghz hidden network created by the device and these follow the channel of my router i.e. if I move my router's channel to avoid conflicting channels these move to the new channel thus competing for the air space with my router, as shown on a spectrum anaylser.How can I turn off the AP side and just have it as a client?
