I'm creating elevation profiles to update some pre-existing trail maps in a very mountainous region of the US. I've been using the "Ready to Use" Profile tool successfully, but just realized that the horizontal distance of at least one of the segments is coming out very different than the distance from the Calculate Geometry tool (off by ~2.5 miles). I have tried using a variety of different tools (the interactive Profile tool, and Interpolate Shape) to create the elevation profiles, and everything is getting the same horizontal distance for the segment -- which is still off from the calculated distance. I've also tried things like reprojecting the segment line and even moving it (using the editing tools) thousands of miles to see if that makes any difference, and the behavior is the same. I'm at a loss to explain this, and would appreciate any insight that can be shared! There are no error messages or even warnings coming up doing any of this. For reference, I'm using ArcPro 2.8.1.
