I’m trying to target fields with jQuery to create calculated values and populate the ACF (pro) fields, and i just realized the hidden field the select2 populates has the SAME ID than the select2.
Was that on purpose?
 was not selecting the “only field with ID”… but the FIRST of the two.
Can you be little more specific about the type of field. I just tried a relationship field and only found one occurrence of the field id when inspecting the element.
