Speaker Fields not in Post Meta

We are using the WP REST API to create an app, one of the requirements is to be able to update the fields for a speaker externally. We can see and update the post metadata for all fileds, except for the speakerrepeatable fields (image and url)
When I look at the post meta in the database it is all in a single string, like this:

speakerrepeatable
a:1:{i:0;a:2:{s:29:”speakerrepeatable_socailimage”;s:4:”1405″;s:27:”speakerrepeatable_socailurl”;s:29:”https://www.facebook.com/ieee”;}}

If I make a custom repeatable filed of my own, it looks like this:
speakerresource
a:1:{i:0;a:2:{s:13:”resource-name”;s:6:”File 1″;s:17:”resource-location”;s:11:”www.box.com”;}}
resource-name
File 1

resource-location
https://www.box.com
And the resource-name and resource-location are passed back in the meta. Your repeatable field is not. How can I change this?
