Strange bug - Ring floodlights motion warning keeps turning off by itself

Hi AllI hope someone can assist with this, I have 2 ring floodlight cameras (along with alarm system and doorbell) and I would like to use the motion warning feature, at the moment i'm getting very strange behaviour.When I switch the motion warning on manually it warns me that "this feature is controlled by your mode settings" and will be reversed next time I enter disarmed mode.The issue is when I go into my mode settings and then cameras, for both floodlight cameras I only get 2 options, motion detection and live view, there is no way to set motion warning settings for modes, has anyone had this behaviour?Thank you for your help
