Inline Entity Form ships with two widgets as Inline entity form - Single value and Inline entity form - Multiple values when I use Inline entity form - Single value, I only get add entity form and when I use Inline entity form - Multiple values I get option to add/edit both.
what I was expecting to see to have both add/edit with Inline entity form - single values with only difference of not allowing to have multivalued field in this case.
Am I missing something?
