When I try to add a new controller it appears with a model already attached to it. For example, I just added a controller for my arches but it automatically assigned the matrix as the model attached to the controller. I checked the layout tab and my matrix is link to my matrix controller. Why is xlights automatically assigning the matrix to any new controller I add? I have tried to click where it shows the model associated with the controller so I can edit it but it won't let me. Any ideas?
