[2020] Can't edit Beacons anymore after today's v11.40 update.

I can't edit beacons anymore, this blocks me from making it hide and appear when need. Already placed and configured ones still works, but i can't edit new ones. I'm making a adventure map, and that is essential to help the player traverse throughout the map and show new objectives.
