Getting node format error for article content type

Getting incorrect node format for particular content type, while other articles seems to work fine with the same content type. I tried exporting the content/duplicating it, but this changes the publish date.

Is there any way to change the format retaining the publish date?

The [object object] can indicate that you are turning an object into a string before using it as a parameter. Can you share your code?
