I guess I have another bit of advice. To tag a bit more onto what I said before, it's worth noting that setting the construction stage may introduce an interval modifier.
For example, in my workspace, if I set the corridor's stage as Phase A, the interval modifier drops special cross sections and processes cross sections at every fifth cross section according to whatever the template drop is set to. If my template drop says every 5 feet, Phase A cross sections are created every 25 feet. If I set the same corridor as Phase B, it generates a cross section for every 5 feet along the alignment, plus one at each PC, PT, VPC, VPT, and superelevation key point, etc.
So bear that in mind and look at your settings. To get these design stages details, you might find them in the Project Explorer under Project Settings / Corridor Design Stages, or using the key-in "civil display browser" and looking for the corridor. (I think I've seen this last option yield these details. You may need to do some digging in there.)
