radions + wxm issue

I got 5 new radion gen 4 pro but I can not get them to work with the Apex controller. I did upgrade the firmware and them updated the WXM module and then the RF as well. every time I want to pair them, WXM will turn them off the stops. it can not turn them back on, so the programming did not finish. also in my apex fusion I have found the new tiles but it shows they are missing. any one can help?
