ListView ObservableCollection Selection

I have ListView with GridView inside (in order to divide ListView for some columns). I bind ObservableCollection of some objects with that ListView.DataContext when main UserControl is loaded. Items show up but when i create two objects which fields have same values (and put them to observable collection), that new items show up in ListView. Problem is that, when user clicks and select one of the new item - both select.

When value of one of mentioned objects changes (and is different) problem doesn't exist, ListView treat them as it should.
