Firebase Realtime Database in console not working?

Question

When I try to delete or edit a node in my realtime database, I always get the info that I have to select a key with lesser elements to change something, else it is in read-o

Update 5/24/17: Problem resolved. Works now.

It seems the ability to click on a child node and promote it to be the top element of the tree is broken. Doesn't work for me either, even on a small database that is not in Read-only & non-realtime mode. I'm almost sure it was working a day or two ago.

I'm seeing the failure when using Chrome. Just tried Internet Explorer. Its works there.
