WPForo + User Custom Fields - Registration form entries are not posting  

Hey,

Can you help me figure out why my additional fields are not being POSTed on registration submit?

I have a custom implementation of WPForo that accepts an input from jQuery, but everything is working with the exception of the data being  sent. 

I am using the setup that allows the user to set their own password. Below is the Header payload. Fields not present here are: display_name (wpfreg_display_name), and a custom field (data_field_1f5e0aa).

I am dynamically adding data to both fields via their ID (#wpfreg_display_name). Is there something I'm missing where the actual field name isn't receiving my data? I should also mention both fields are locked before the send is initiated. 

I went through the php files for both wpforo and the plugin and I have a couple of ideas, but if you could help me figure out what I'm doing wrong I'd appreciate it!
