Dreame starts cleaning without a schedule

My Dreame starts cleaning every evening at 6pm, despite there being no scheduled task at that time. I do have a cleaning schedule in the mornings at 8am; however nothing at 6pm. I have checked settings in the app and can find nothing that might be causing this. Can you point me to what I am missing? Thank you.

Have you tried setting up a 6pm activity and then deleting it?

Good idea. I will try that. Thank you!
