Yes I couldn't agree more. When I read it today it IS very confusing . I will close this issue cause the main problem is solved. And I'll start a new thread with my new issue and with a MWE.
When I build it says in the beginning: "Running pdftex..."
And on my laptop it says: "entering extended mode" Which compiler is set for the pdflatex format (MiKTeX Options->Formats->pdflatex->Change)? Should be pdfetex, not pdftex.
