Custom Fields all have the same data in a Custom Post Type

Howdy,

I’ve installed the plug-in and successfully exposed an API end point for a CPT, including a handful of custom fields in the response. All custom fields display the same data, the first custom field generated:

Incorrect output:
project_client":"acme Inc.","project_title":"acme Inc.","project_lead_paragraph":"acme Inc.","project_brief_description":"acme Inc.","project_long_description":"acme Inc.",

As you can see – “acme Inc.” is the value of ALL project_ fields. Each db field contains the correct value, but each custom field uses the value of first custom field at this API endpoint.

Debug on my local and web apache servers shows the following error when pinging a specific item:

Any idea what could be up with these 2 issues, and if they are related? Suppressing the error message is not the end of the world – if the data was accurate.
