You may be encountering auto-ordering (or lack thereof) of the vias. If you add a via by right-clicking a point on the map, pick create route, insert via, then it doesn't number them as you add them, it numbers them as they will be encountered along the route. If you add a via that lies between 4 and 5, then 5 becomes 6 and the new one becomes 5.
If you have the advanced button selected on the route tab, and you use the via button from there to add a via, it goes in at the point that's highlighted in the list, rather than auto-ordering as it's added. If 8 was highlighted, then the new one becomes 9, even if it falls between 1 and 2.
If they're out of order, you can highlight a via in the advanced window and use the arrow buttons on the right to move that via up or down in the list.
Are you the reason I'm so far above average?
