In SQL Server INSERT ... VALUES clause UUID is not substituted

Teiid 8.4, SQL Server 2012 Express

I'm inserting into table with uniqueidentifier field

INSERT INTO SOME_TABLE(some_uuid, some_ts)
VALUES (uuid(), now())

and get something like

195 Remote org.teiid.translator.jdbc.JDBCExecutionException: 195 TEIID11013:TEIID11004 Error executing statement(s): [Prepared Values: [{ts '2015-02-24 21:02:23.803'}] SQL: INSERT INTO "DS"."dbo"."SOME_TABLE" ("SOME_UUID", "SOME_TS") VALUES (uuid(), ?)]

However if i use INSERT ... SELECT clause it's substituted normally:

INSERT INTO SOME_TABLE(some_uuid, some_ts)
SELECT uuid(), now()
FROM SOME_OTHER_TABLE
LIMIT 1
