Unable to Switch off Motion Schedule

Hi All, Has anyone experienced this issue with the Ring Doorbell? According to my Ring app, I have a Motion Schedule set up to not give me motion alerts during certain times. I recall setting something up when I first installed the device. However, I want to get alerts now, but when I try to toggle the Motion Alert button to ON, it asks me to disable the Motion Schedule first. But when I click Disable, it reverts back to the original state. If I go into Motion Schedules, there aren't any set up at all. I've uploaded a video showing what happens.  Can anyone suggest a solution? I've tried deleting the device and re-installing it, but it seemed to remember all previous settings. Thanks
