I have a simple 3 record file of country capitals that I created with Notepad++ text editor. I imported it into ArcMap 10.3.1 on Win 10 Pro (fully updated), using File, AddXY.
-90.5069,14.6349,1
-87.1921,14.0723,2
-89.2182,13.6929,3
I did File, Data, Export to create a shapefile. I set a projection of GCS_WGS_1984. The imported file table has the following fields (see attached PNG file): FID, Shape, Field1, Field2, Field3
However, now when I try to project the file from Geographic to UTM16n the resulting projected file is missing the first two records. No records are selected in the original file before the reprojection. I have tried this multiple times, restarted ArcMap, rebooted the computer, and now I am crying for help. A PNG of my tables is attached for proof of this annoyance. Why is this happening and how can I make my ArcGIS return to "normal"?
