pickerFieldCustom to not select a value.

Hello p2005 

Please share the code snippet. The simple answer is when you are creating the ER for Array Picker used in the suggestFunction of pickerFieldCustom, you need to remove the Great Britain and Northern Ireland values from the list that you are using for labels and identifiers.
