Country prefix missing when value set to empty string

[Criez's]

Hi, currently I'm using your libraries as phone number input. But I encountered an issues where if I click the reset button which resetting the value of sender into an empty string. It forces the country prefix (+62) into null. Only leaving the flag it self

this is my code

<InputPhone
                        label="Sender Number"
                        value={sender}
                        onChange={setSender}
                        country="id"
                        onlyCountries={['id']}
                      />

for the examples after I set my sender state into empty string

issues resolved by setting setState into ('+62')
