Why cannot my forms/subforms become moveable

I am trying to redesign my database (Access365). I want all my forms and subforms to be moveable, but when I try to change the moveable option in the property sheet into "Yes" it is not accepted. I have tried to find some general options for my database, but found none. I hav no code. Biorn Veiro

This is an application wide setting, while the Moveable property is per Form.
