I'm still on arcgis 10.2.2 and I think I have something similar but I'm not sure. So I had a long integer field and it was populated using the field calculator and for some reason it was limiting everything to 9 characters. So I went and changed it to 10 characters and it automatically changed it from long to double. I guess this is supposed to happen? Then I went to load a shapefile's info into a database's shapefile, and it loaded all the columns correctly except for the one it turned into a double (I had to go into the database and change that column into a double first as well to match). Instead of loading all 3000+ rows, it only loaded one row for that one column and it gave some huge negative value (-2147483648). No idea what's going on.
