Issue
Using ${URI_REF} on notifications, the link shows the project state field value instead of the project number.
Cause
The issue is caused by the below dictionary override on the state field of task table where the default value has been override and set to true.
So, on project table, there are two fields with the display set to true(number,state) and that's why the link is pointing to state field.
/sys_dictionary_override.do?sys_id=c0ddb2f1dbdac850dd9fe1aa4b9619e4
Resolution
Uncheck the override display value on the above sys dictionary override.
