In ArcGIS Pro, every time I delete fields, either with the Geoprocessing tool Delete Field or in the Fields -> Design view, deleted fields do not disappear from the session! Messages indicate that fields were dropped but they still appear in the Field Design view... And if you try to re-create these Fields with Add Fields, the message tells the fields already exist!
For the time being, the only workaround I found is to restart ArcGIS Pro to "refresh" the session. It looks like a bug!
Anything wrong with my approach?
