BlueprintImplementableEvent for Component will not Show in Editor

Yeah, I have tried everything from renaming the function name to restarting the editor. It is not showing up in UE 4.16 now for me. Below is the code in the header file. Yes,TCPIOJsonValue is a blueprintable UObject. It works properly when using the Delegate method. The delegate code is commented out for now to see if I could get the Event one to work. The delegate code works just fine and shows up in Blueprint Editor properly.
