WORKAROUND 1
Increase the compatibility level higher than 120.
Compatibility levels of 120 and below do not technically meet the requirements listed in the Deployment Guide because it effectively turns the Azure instance into a version below Azure v12.
WORKAROUND 2
Please contact Support for a hotfix for this issue for when compatibility level is set to SQL Server 2008 (100)
