Whenever I click on a training in my calendar (training plan), you can see, that a window opens and then immediately closes. It only happens when you click on the part of the training plan (bigger boxes) if you stay with the smaller ones in the upper right corners everything works fine. When you click on a big box, later the smaller don't work as well.
