Unset Default Filter Values Reset on Dataset Change Leading to Inaccurate Visualizations

[WillHannon-MCB]

When a filter is applied without a predefined default value in the configuration JSON, the filter’s value is reset each time the dataset is changed. This behavior could result in misleading visualizations because users may be unaware that the filter values have been cleared.

The solution is to either:

A. Track the value of the filters across datasets. This can requires the same filters to be present in every dataset. This isn't currently a requirement.
B. Add sensible default values to the JSON and warn the user if a value isn't specified.
