Dubious Geoprocessed 3D layer behaviors

I’m trying to animate a linear path. I start w/ a datafile of 8000 lat/lon/elev points.

From the tutorial, I learned to apply the following geoprocesses:

  1. Make XY event layer
  2. Feature class to Feature Class
  3. Points to Line
  4. Split line at Vertices

I don’t have any problems doing any of this in 2D. All of the geoprocessed output layers work and I can continue w/ animating the final geoprocessed (Split line at Vertices) layer. So I’ve proven sufficient competency in 2D.

But in 3D, everything goes awry. For 3D data I am using the project data from the 3D basic tutorial “Create Points on a Map” http://pro.arcgis.com/en/pro-app/get-started/create-points-on-a-map.htm

After applying a geoprocess (eg. Feature to feature, points to line, split line at vertices) the resultant layer should match exactly (and thus sit on top of) the input layer. Correct?

But many if not all the resultant output layers do not match. Many of the resultant output layers (when they’re visible, often they’re not… ☹ ) do not match the position of their input layer and thus are translated (seemingly randomly) some meters up/down/right/left (albeit the shape is retained).

I’ve exported & examined the shape file data to no avail.

I’ve deleted/updated/etc. cache settings, and project spatial index settings all to no avail.

I’ve played w/ visibility ranges.

In fact changing layer properties seems to have no positive affect nor yield any illumination on the problem.

Are these ArcGIS Pro bugs? If yes, what can I do? If no please tell me what I’m missing. At this point I have no faith in my ability to geoprocess or otherwise control my ArcGIS Pro layers. Thank you in advance for any help or advice (including anything I’ve tried before).

Background info:

Using ArcGIS Pro 2.1.3 (auto update on).

I got my info on how to do this from this quick useful demo: https://www.youtube.com/watch?v=tq4rzFPXwr4 (please note my problem/questions are not about animation per se. My problem is with the behavior/visibility of the resultant 3D geoprocessed output layers.

My data represents a single drone trajectory flight path with 8000 lat/lon/elev points in GCS WGS 1984.

Screenshot 1) Why are the layers shifted? No coordinate translation should have occurred in the above mentioned geoprocesses. One layer should be sitting on top of the other.

Screenshot 2) Zoom in 700m and the green layer starts to disintegrate and the red is stable. Why? Why don't both layers behave the same?
