Page background color from a stylesheet

Questions
1

Hello everyone,
I installed version 14.2 and a Stylesheet I created did not work correctly like in other versions. The page background color I defined is not applied. I use the following code to create the Stylesheet:

CreateDocument[ Notebook[{Cell[StyleData[StyleDefinitions -> "Default.nb"]], 
   Cell[StyleData[All, "Working"], {DockedCells -> Cell[ToBoxes[ExpressionCell[set1]], "DockedCell", 
       Background -> "None"], Background -> RGBColor[1, 0.96, 0.90]}]},StyleDefinitions -> "PrivateStylesheetFormatting.nb"]]

Can someone help?

Regards,
Sinval
