Hi,
Not sure if this is a bug or if this is in FlexSim already for a long time, but I noticed something strange.
When you add a dashboard to your model and later on delete it, it still stays in the experimenter.
The experimenter even collects all data for some charts. So you don't see the graph in the dashboard, but you do see it in the experimenter. You can see this in the attached example model with the state pie, which is in the experimenter but not in the dashboard.
