Resolve Stratus Admin console error saving map config: Please choose a valid option from the list



Running the Admin Console and trying to save a Map config and generates the error: "Please choose a valid option from the list" and then cannot save the map config.

The error is generated because at the Admin Console>Map Config>Settings tab, the "Printing Preferences" has no option selected within the drop-down.

To resolve, the Admin must use the Printing Preferences drop-down and select one of the 3 printing options and then save that choice.
(Enable Printing, Disable Printing, enable Scaled Printing)
