Bug fix: "Filters that can "break" the app: currently, your filters work based on the assumption that they must take on a value. However, if the user accidentally click on the "x" in the filter, they can clear the filter and "break" the app by causing certain plots to only show their axes. If possible, make it so that the filters cannot be cleared." #117
This is explained in the drop down text at the top of the dashboard.
