Jira is Picking wrong Priority which is not available in my Project

[Madhu Reddy]

Jira is Picking the priority which is not attached to my Project priority scheme..

Could you please correct me If I was wrong..

I have used Universal Post function metric from Workflow enhancer plugin and added the code as follows..

My Project priorities are Blocker , High , Medium , Low.

Code :

{Priority}== "Blocker" || {Priority} == "High" || {Priority} == "Medium" || {Priority} == "Low"

and Expression must value to : True

When I try to add I am getting the error.. Oops error occurred and I am unable to add the rule.
