In Maple Design of Experiments 2019.1, from the DesignOfExperiments[DOEInputGUI] user interface page, in the RSM Settings -> RSM Table -> Adaptive RBF settings, the following actions will result in an error:
1) Updating the lower bound for the RBF No. (it should always be equal to 1).
2) Using Different bounds of RBF No. for different outputs (this is not supported).
