Dry Wall change from default 96" to 144" unsuccessful

[UCBD317]

Hello!
I am Home Designer Pro 2025, and I am a beginner.
I am trying to change dry wall from the default 96" to 144". 

I went to edit -> default setting -> Walls, and edited the wall types (define, dry wall, double click to change material) for both exterior and interior walls.

When I do the list of materials, I see both 96" and 144" dry walls listed in the wall board.

When I select the 96" and do right click to find object in plan, the entire inside area of the house is grayed out.

Is there anything I am missing / not considering?

Thank you for any help!

do not think there is a way.

Should only affect the material list when you calc for rooms, floor or house..

 

List gives # sheets so you could do a little math - take: #sheets * 8/12  = Q12ft you need
