Not every multi-edit command isn't working but enough for me that I can't use it at the moment.
I've tested also with 10.11.05 and contacted the GTAC and the answer was... don't use multi-edit.
- select some APs, 5GHz on, 40MHz, channel-plan all, channel auto >>> result all APs are stuck in scanning forever.... please reboot the AP >>> all APs are on channel 36/40
- select some APs, turn on radio1 >>> AP reboot
