Movement detector problem

Hi there! In the very lasts updates of bOS Config, I've found a problem by adding the Movement Detector task. It shows me the red circle of problem, but it's still empy, every field is not filled and there's no error, so I don't know why it happens.

Actually, when I click the errors, it shows me

Tasks\Movement Detector ([Error]Disabled)

but I don't know what it means. 

Is there any way to remove the error? Thank you!!
