We have recently switched to Revit 23 from 21. In doing some, the Print sheet order index no longer functions in the sense that the combined sheet set as a PDF does not match the order of the schedule it is printing from. When I shift click to clear non printable characters, it still prints out of order.
It has been fixed by Use OrderedListView when printing on Revit 2023 and newer by coditect · Pull Request #1756 · eirannejad/pyRevit · GitHub
