Copy-pasted part of an excel sheet into a layout. All color information gets overwritten by the layer color when I try to plot, either a physical copy or to PDF. Googling suggests changing the plot style table but nothing I select on the plot menu fixes the problem and the layer plotstyle is greyed out and cannot be changed.As recently as a month ago this was not a problem. Any ideas?

Update: The print preview shows a fully colored version despite it printing in the layer color. I don't know if that means anything.
