Like the title says on 1 particular vehicle suddenly none of the tunes will allow me to edit the trans diagnostics, fuel system, system, or speedo. All other vehicles will expand these menus and allow me to make changes. I have made changes to these tables in the past, so I'm baffled as to why I can't now. Any ideas? My software is old as hell but I don't see that being a factor here. I've attached an image for reference.
