Craft duplicate do not make random text contents.
Creating a random image works well. Text content does not work.
I've left a question like link in the past and it's been resolved with your kind feedback.
However, when I used it yesterday, a random image was created, but no random text was created. I hope to solve it.
++++ Additional questions
Is it the default behavior that random content is not created when I copy layers or text (using craft random "Data") with the "option" key and mouse? (Without using the craft "Duplicate" feature)
A random image is created using the duplicate function.
However, when I copy it with 'opt key' + mouse or copy it with cmd + c, cmd + v, random image can not be generated.
I wonder if this is a default feature and it is also a bug related to my issue.
