Comment:

 Hey @elliotcondon - Sorry this never got any attention.

 Would you be able to put together a short example plugin which shows the
 behaviour you're seeing? or steps on how to recreate it easily using ACF?

 Looking at the code, and testing it with browser-inserted fields, it at
 first looks like it's working as expected for me, but I might be mis-
 understanding how you're expecting it to work, or I might be missing a
 crucial step.
 {{{
 JSON Posted:
 [
 ...
  {
     "name": "testing[]",
     "value": "A"
   },
   {
     "name": "testing[]",
     "value": "B"
   },
 ...
 ]

 Resulting var_dump( $_POST ):
 ...
   'testing' =>
     array (size=2)
       0 => string 'A' (length=1)
       1 => string 'B' (length=1)
 ...
 }}}
