Please provide an screenshot of your problem or at least tell us where you see this. We are currently in the very end of the transitioning phase, so the old one may be available to you still and you see the error there. In this case this error won't get fixed anymore.

No, CUI is gone as I'm on current master. I just reproduced in on the demo instance, I can create screenshots there if wanted.
