Ok, I haven't used it so I can't really help any further. It makes no sense to me that what you posted is the output of dd($request->all()). However you are submitting the form (which I see lots of inputs not with an actual <form>) is not working properly.
You should only be seeing the input names/values in the $request when you dd() it like a normal form submission.
like
[
'name' => 'the name you entered',
'reference' => 'the reference entered',
'latitude' => 'latitude entered',
'longitude' => 'longitude entered'
]
