I am trying to use the MMM-ModuleScheduler module to show sports league tables only during the relevant season. eg only show the Formula1 standings between March and November and football league table only between August and May. Each of the modules is in the same screen position and uses MMM-Carousel to rotate between them.

My config is

               {
                        module: 'MMM-ModuleScheduler'
                },

and then for the MMM-Formula1 module

                {
                        module: 'MMM-Formula1',
                        position: 'top_left',
                        classes: 'scheduler',
                        config: {
                                type: 'driver',
                                maxRows: "5",
                                calendar: "true",
                                fade: "true",
                                module_schedule: {from: "* * 1 3 *", to: "* * 30 11 *" }
                        }
                },

No matter what I have tried, the MMM-ModuleScheduler causes the mirror display to be blank.

If I comment out the first section of code above then the mirror runs fine. This seems to suggest that the issue is in the module: statement?

What am I doing wrong?
