Hello.

This system Author block is optional and can be easily used instead of the default one. You just need to go to Studio -> Pages builder -> select module (for example, Posts) -> select view content page (for example, View Post) -> click with [Add Blocks] button. In the popup select System -> search for 'Author' block and add it.

Then deactivate the default 'Author' block and move the new one in the right column.

That's it.
