I have the same problem with SQL2012 (11.0.5058.0) on many tables.I checked for reseed and set identity_insert. It's not the case.
If there is a unique constraint insert fails. It not sql server inserts duplicates.
@SQL-Lover Thanks for posting.
No problem.
It may help others if you mark my last post (the trace flag) as solution.
Thanks.
