Shapefiles are not showing all features

[Ayad]

I've been having an issue with displaying all features from downloaded shapefiles (e.g. https://www.pasda.psu.edu/download/pamap/pamap_lidar/cycle1/BL/South/2006/40000000/42001330PAS_bl.zi...)

Those are breaklines and should be showing more than 2K features. The same shapefile displays perfectly in ArcMap, but in ArcGIS Pro it shows only one line segment. I cleared layer cache, general display cache, I made sure there are not definition queries/filters set, and no scale dependencies.

I tried even Adding a Spatial Index to the shapefile with no success. I tried importing it to the project's geodatabase and it exports only this single line.

I had to create a file geodatabase in ArcMap and import the shapefiles there, then open the geodatabase in ArcGIS Pro in order for it to work. It seems counterintuitive to me, especially that some other shapefiles do not have this issue (e.g. contour lines: https://www.pasda.psu.edu/download/pamap/pamap_lidar/cycle1/CONT/South/2006/40000000/42001330PAS_con... 

Am I missing anything? Is there anything else I should be trying?

I checked as well, there is some geometry issue or connection to the geometry.  

I tried a calculate geometry on the file and only the first record had a length or a start and end coordinate.

I would contact the originator of the data (in the xml or html)

That's interesting, I'll definitely let the data originator know. The more interesting thing is that I used the same exact shapefiles about a year ago in ArcGIS Pro with no issues (earlier version of Pro, I think 2.7?). And they open with no issues whatsoever in ArcMap.

tried most, but I am not going to try the utility... it could have been a dud download, but they should be aware of it in any event
