There isn’t a way around this directly. The reason this happens is that ACF stores the values as an array, like this

$field['choices'] = array(
  2850 => 'Aarons Pass'
  2176 => 'Abbotsbury'.
  2046 => 'Abbotsford',
  2795 => 'Abercrombie',
  2795 => 'Abercrombie River',
  2325 => 'Aberdare',
  2359 => 'Aberdeen',
  2336 => 'Aberdeen',
  2350 => 'Aberfoyle',
)

anywhere you have two array indexes of the same value some of them will be cancelled out.
I’d suggest using values like ‘2759-1’, ‘2795-2’, or something else that will uniquely identify them and then deal with this in your PHP code.
