json-editor: format: checkbox does not send info over POST request but selection2 does

I don’t know if this is a bug or i am missing something but when i format a field to format: selection2 and send my form in through a POST request. I get the selections information in the request, but when i switch the format: checkbox the schema renders fine and works but the POST doesnt send its selections through the request post. Any thoughts as to what could be causing this?
