Error : "The field named RN_TEST_ID does not exist in the project" when I try to configure Automail

Hi!

 

I am getting the error : "The field named RN_TEST_ID does not exist in the project" when I am trying to configure Automail.  On click ing the OK button, the user list does not show up.  I have checked and it is there in the RUN table.

 

This is only in one project.  I am running QC version of ALM 11.52 (patch 2)  

 

I couldn't find anything online.  

 

Do you have any idea what I can try???  I am the admin and have access to the servers in case I need to do anything.
