now I'm really confused

where are you seeing those errors?
I haven't seen any errors when working with the scene
the scene should consist of 2 cabinets, 1 countertop, 1 monitor stand, and 4 "monitors", and 8-10 lights throughout the scene .... (same as image in my finished project post, with the addition of 4 lights for monitor screens)

and rendered in seconds ??

any way you could send me back the file that you modified so I could look and see what was changed
and hopefully understand what I did wrong in the first place?
I would appreciate it, and definitely appreciate you taking the time to look at this in the 1st place.
