Relationship Field not linked in Posts Table Pro

Describe the bug I'm submitting this based on the discussion here: https://wordpress.org/support/topic/separating-pods-in-template/

I'm using a premium plugin called Posts Table Pro. It uses Pods to build the database. We're using it as a document library. Initially everything was working perfectly except the authors (which I added as a pod) were displaying alphabetically. The authors have to display in order of their contribution to the publication so it was suggested by Pods support that I enter the authors using a relationship field. I did that and it works perfectly on each separate publication page, but once I added the Custom Field to the Posts Table Pro shortcode it adds the author names but they are not linked.

To Reproduce Steps to reproduce the behavior:

Go to http://test.otru.org/publications/

Expected behavior Ideally I would love to have the authors linked so that people can sort the table based on their name. This is what the date, publication type and keywords do now.
