Hello Reuben! Are you renaming the elevations at all? If you do, ConDoc always looks for the scenes it is consecutively numbering… If it’s not there, it will start at 01 again. Try just adding elevations, and make sure you pick the same “CD” or “SD” visual style when you get the pop up. Let me know if that works for you, we have never heard of or seen this behavior. Thanks!
