React Native - RNPickerSelect - Empty value before the first dropdown item

Question

When I use RNPickerSelect I get my items in the dropdown, but right before the first one there is an empty value which I want to remove. I just want the first item to be selected automatically. Does anyone know how to solve this?

The interface I use to declare the props and reuse them in the parent component

interface AutoSuggestProps {
      types: IRequest[];
      onSelect: (item: string) => void;
      disabled: boolean;
      placeholderLabel: string;
      title: string;
      dropdownValue: string;
      setDropDownValue: (val: string) => void;
    }  

Here I am creating a component which uses the React Native component

 export const DropdownList = ({
      currencyType,
      onSelect,
      disabled,
      placeholderLabel,
      title,
      dropdownValue,
      setDropDownValue,
    }: AutoSuggestProps): JSX.Element => {
      return (
    <View>

I have used it like this because it was only way I could get at least the first item. But the problem is on top of the first item, there is an empty element that is selectable

       <RNPickerSelect
    disabled={false}
    value={dropdownValue}
    onValueChange={el => {
      setDropdownValue(el);
      onSelect(el);
    }}

If I use the placeholder like this placeholder: {{value: dropdownvalue, label: dropdownvalue}} , a label 'Select item is printed' which I don't want.

  placeholder={{}}
    items={types}
    useNativeAndroidPickerStyle={false}
    Icon={() => {
      return <DropdownArrowSVG_noFill width={(width + height) / 50} height={(width + height) / 50} fill={dropdownColor} />;
    }}
  />
</View>
)
})
