Parse XML data not all available for next node

I am receiving xml data from a Gmail account. Each email body is run through the Parse XML node that correctly parses the data. I then want to save the data to another software via a Call API.
The problem is the customer name. The Parse XML pulls out the first_name, last_name, and full name. However when mapping the Call API only the full name is available even though the output of the Parse XML shows all 3.

1. Relevant Screenshots

Please share screenshots of your scenario, any error messages, relevant module fields, and filters in question? It would really help other community members to see what you’re looking at.

2. Scenario Blueprint

Please export the scenario blueprint file to allow others to view the mapped variables in the module fields. At the bottom of the scenario editor, you can click on the three dots to find the Export Blueprint menu item.

3. Output Bundles of Modules

Please provide the output bundles of the modules by running the scenario (or get from the scenario History tab), then click the white speech bubble on the top-right of each module and select “Download input/output bundles”.

Providing the input/output bundles will allow others to replicate what is going on in the scenario even if they do not use the external service.

Following these steps will allow others to assist you here. Thanks!

Ok thanks. I am attaching the screenshot of the information for the customer name that the Parse XML outputs, then a screenshot of the data available for mapping. Finally I am attaching the blueprint.
