Due date in Asana Form to Jira Sync

I have spent hours trying to sync Jira and Asana. The ticket will link but none of the information in the ticket (due date, custom fields) will make its way to the fields in JIRA. My custom fields (Actual Client Deliverable Date and SOW Expiration Date) in Asana do not populate to map to JIRA fields. Instead they appear as “JIRA Actual Client Deliverable Date” and “JIRA SOW Expiration Date.” I do not want to use the “JIRA” fields mentioned, I just want the custom fields from Asana. Do you know why they are populating like that (with “JIRA”)?

I can’t even delete these fields from my project - I only want the custom fields.

Customize → Apps → Jira Cloud → Data Sync Settings

Here you can choose the sync settings for custom fields, due date, assignee. NOTE - I am experiencing a bug that does not sync the assignee or due date to Jira. If the changes are made in Jira, it reflects in Asana. I have been working with support to unpack the issue but so far no luck. I have to manually add the due date and assignee to each Jira ticket.
