Revit print scale not setting

Hi… I’ve encountered an issue when using graphs (my own and ones created by others) set up for printing from Revit. Everything works fine apart from if the project has previously had a different plot scale set… ie if a plot has been set zoomed to fit a smaller sheet size. I’ve noticed other people have posted online about this but don’t know if anyone has managed to resolve it?
Basically, what I’m wanting to achieve is to either plot a full size set of prints or a reduced sheet size set by running the relevant graph but at the moment, the relevant node is not managing to change the Revit print zoom setting.
