Publish using Page Setup override won't override

[LGB]

Hello,

 

I'm using Sheet Set Manager in Autocad 2011. I'm using 'page setup override', and as plot area 'print extents'. So far, so good. Until someone forgets something outside the title block, and the extents feature is not good anymore (several people working in the same projects).

 

So, I decide to use as plot area 'Layout' instead, typing the X & Y to determine the area to be plotted.

 

Now, the setup "override" doesn't override. It’s using the drawing plot area from the drawing itself, which completely defeats the purpose. Am I missing something? I'd appreciate some help. please.

 

Thanks in advance
