Modifying the default value of a UUserWidget parameter declared in a c++ in blueprints appears to have no effect after compiling. The default value will reset back to "none".
Additional info. The property was set to be "EditDefaultsOnly"
Result: The Property will be set back to "None"
Expected: The property value of test widget would be retained after compiling the blueprint
