Solved!
By referencing this page: http://www.advancedcustomfields.com/resources/checkbox/
I noticed the code for displaying multiple values on the frontend is:
<?php echo implode(‘, ‘, get_field(‘field_name’)); ?>
So simply by using this but removing the comma it displays the multiple selected values but without adding a comma between each.
<?php echo implode(‘ ‘, get_field(‘field_name’)); ?>
I hope this helps someone else!
