DeNoise AI 3.0.3: Changing DeNoise parameters with keyboard does not work when Auto is selected

In Topaz DeNoise AI 3.0.3, when Auto is selected, it is not possible to change the DeNoise AI parameters with the keyboard without first deselecting Auto. After typing a new value and pressing Enter, the value and slider reset to the previous value.

Moving a slider with the mouse correctly disables Auto and keeps the new value, and entering a value by keyboard should have the same result.
