When I query to select a set of features from a feature class layer and export it to a different layer. The resulting new layer has more features as compared to initially selected.
For example, X is the original feature class on which I applied selection criteria via the 'Select by Attributes' option. The resulting selection had 10 features. Then I right-clicked on Data > Export Features and exported it to a new feature layer. When I add this layer to the map, I can see 21 features! (and not 10 that I had filtered).
The selected 10 features are part of the set of 21.
But, why am I getting 21 instead of 10 when exporting to a new layer?
