C# combobox duplicate items AutoCompleteSource ListItems

I've found a small problem if you want to use a bind dropdown combobox, that has AutoCompleteMode - Suggest and AutoCompleteSource ListItems: if you have two or more duplicate display members(even with the Value Member different), upon select, lets say, the second duplicate item, the combobox automatically selects the first duplicate item.

To resolve this isue:
