CMS844 CQL Library Editor shows that CQL is correct when initially clicked into and there are no errors boxes in logic.  When Save button is clicked - even without making any changes - an error message comes up stating that the CQL file could not be saved due to an identifiers issue.  There are still no error boxes in the logic.  I and my team members have reviewed all logic multiple times both in the CQL Library Editor and in Definitions and have not found a reason for this error message.  The logic is is very similar to CMS529 and that measure is not having this issue.  Please see attached screenshots.
