Defects Missing From Traceability Report

We recently upgraded in place our Jira Server 8.8.1 and Zephyr for JIRA - 5.5.2.55208569 to Jira Server 9.4.1 and Zephyr Squad 9.2.0.92009706.  Everything looks great overall.  The only issue we have is that the Defects are missing from the traceability report.  I can see the Defects linked to the Test when I open the Test.  

I tried clicking the Reset button for "Configure LinkType for Test --> Defect relation" but it was already set correctly to Related To.  I have re-indexed the projects involved, but no luck.  The defects column is blank.  It works in the old version using the same criteria.

Any ideas?
