Can not turn off Wall Justification Line Can not see Diagnostic display on status ba

Can not turn off Wall Justification Line.

Help recommends to do it on Diagnostic display, but I can not see Diagnostic display on status bar. I need it extend wall to face of another wall, no to justification line. I have AutoCAD architecture 2014 from Factory Design suit. Is something wrong with interface setting? It is just out of the box and I am trying to do some learning exercises.

Thank you for your help in advance.

Looks like this should be addressed to the Architecture Forum. Perhaps a Mod can move it for you.
