I was updating CQL, specifically valuesets, and when I save my revisions, an error pops up, "WAF Issue Encountered" (image attached). Also there seems to be several errors related to 2 specific value sets:

1. valueset "Federal Administrative Sex": 'urn:oid:2.16.840.1.113762.1.4.1021.121'
2. valueset "Glycemic Screening Tests": 'urn:oid:2.16.840.1.113762.1.4.1160.5'

The error codes include:
