files could only convert to 1 type of the time.

As mentioned in your video, files could only convert to 1 type at the same time. It is because you use "selcted". You could solve it by changing the code as follow:

// setSelected(value);
                    updateAction(action.file_name, value);
                  }}
                  value={action.to }

as follow, you also need to correct the type to match the accepted value type.
