If this issue occur in Shapefile, you may try deleting the spatial index from the Properties of the shapefile. ArcCatalog > Shapefile properties > Indexes Tab > Spatial Index > Delete and then Add > Apply the changes If this occurs in a File Geodatabase, you may try recalculating the spatial index from the Properties of the Feature class. ArcCatalog > Feature class Properties > Indexes Tab > Spatial Index > Recalculate > Apply the changes ArcCatalog > Feature class Properties > Indexes Tab > Spatial Index > Delete and Recalculate > Apply the changes Unfortunately for a personal geodatabase feature classes, there is no button to recalculate the spatial index as in File GDB or Shapefile. However the Spatial Index can be recalculated by exporting the feature class again to the same geodatabase or to a different geodatabase. ArcCatalog > Right-click on feature class > Export > To Geodatabase (single) or ArcToolbox > Conversion tools > To Geodatabase > Feature class to Feature Class Hope this helps. If you further face any issues, I would recommend to contact Technical Support for further assistance. Thanks for your help!
