Stop grid from grouping strings

Is there no way to stop the grid from grouping strings that has the same content? if i select any of the Example strings it will select both
also only 1 can have the delete button and if i delete the bottom one it will move the other Example to the bottom, i want it to stop grouping things and to keep the order things are in

You need to use objects that have a distinct identity, see Binding Items to Components | Data Binding | Vaadin Docs

Thank you!
