The same thing happens to me, I already announced it but I haven't seen it yet @ExeldroIt's probably my mistake:
Each time I start OBS with my production scene collection, the last item in my Downstream Keyer list "Overlay Wait" will be visible, although, last time I shut down OBS it was not. So I have to press its hotkey to get rid of it. No big deal, but maybe I'm doing something wrong?
