Kickr won't stop automatically connecting

Just upgraded my Kickr and now it automatically connects as a controllable trainer each time I open Zwift. With my old Kickr, once I selected to ‘forget’ the controllable trainer, it no longer connected at startup. I run TrainerRoad alongside Zwift, so I ONLY want my power meter as the power source for Zwift. I’ve tried deleting the preferences and known devices xml files but it still connects. Any other suggestions?
