Bizarre outlines

Am pretty new in Rhino.
There is box frames in thin lines after making solid box in rhino but the boxes disappear, these box frames cannot be selected, or hided in Rhino 3d, what to do? Adjacent walls are created in visualARQ plug-in…does it affect? If I use show selected that showed those outlines only but no box I created in that same place and the outlines can’t be selected to show!
Here is attached view.
Thanks in advance.!

Hello - please start Rhino without any VisualArq geometry and see if added boxes behave normally.

Also, please run the SystemInfo command in Rhino and copy/paste the results here.


Thanks, I will check it.
