This would be becasue you used the loose file upgrade so the new measure is refered to in the rule but not present in the measure dimension until after the upgrade process is run.
Just run the upgrade process again. There should be no error the 2nd time.
If you are not using Pulse then the new upgrade process must always be run FIRST before any of the updated rux files are added to the directory. Only after the upgrade process has been run to ensure that all the dimension metadata updates are done should the rest of the rux and pro files be updated.
Not sure if you fixed it already @rwang but you need to clear the rule of }APQ UX Instance Client, run the APQ Server Update process which will also add the missing element. Copy back the rule.
