Sorry for my late reply.
I'm building a new site. I'm logged in with my account, with my name, with super user rights in Joomla.
I use only regular Joomla articles, not K2.
Under each article left appears "By ..." followed with my full name from my Joomla account.
I have turned it off, as I write above, see also
https://docs.joomla.org/Removing_author ... an_articleInterestingly, responding, for example, the field "creations date" properly, it can be turned on and off.
That there may be two authors is me unfortunately unknown, have also researched shortly.
Thank you for your patience with me
