Hello All, I'm running the most current version of ARC Pro Desktop and am having an issue when I try to add data to newly created fields in a shapefile (located in a geodatabase and otherwise). My workflow in the past has been simple: Open the attribute table, add a new field if needed, just click the cell and enter text or numerical data, easy. Now it appears to be locked? When I click and type, no data. I've tried setting up new test colums of different types, tried saving the shapefile outside of a geodatabase, ensured that they are not "read only"--All to no avail. It's driving me crazy and I'm hoping someone has some advice for what seems to be a really basic function that no longer works! Attaching screenshot of the field that currently shows all null values
