title: Ionic 5 PickerController remove mug icon when all column values are same
body: <p>I am getting below mug icon when value of all of the columns are same in ionic multi-column PickerController.</p>
  <p>For example, all three column has array of string number ['0','1','2','3','4','5','6','7','8','9','10'] in {text, value} format.
  if set selectedIndex to 0 for all three column then I get this icons instead of '0'</p>

  <p>Is there a way I can disable this so it always shows values instead of these icons?</p>
  <p>Thanks</p>
