Hola Sachin,In testing this issue within ArcMap 10.1, I was able to see both options available. The Undo/Redo option was available within an edit session; I am attaching some screen shots for your review. If you are still seeing this issue, please look into the data or log a webform with us in Support Services. Gracias, Sachin!
