Valid Sql merge statement fails Sql Prompt layout

The below valid sql stored proc fails the layout command in Sql Prompt. Why?

<bbcode>
create PROCEDURE dbo.usp_mrg_JournyxTimeRecs
AS
BEGIN

SET NOCOUNT ON;

MERGE INTO dbo.journyx_time_recs T
USING (SELECT * FROM [[journyx].[dbo].[time_recs] WHERE LTRIM(RTRIM(record_date)) >= '20160101') S

INNER JOIN [journyx].[dbo].[users] U ON S.id_user = U.id_user
INNER JOIN [journyx].[dbo].[users] C ON S.creator = C.id_user
INNER JOIN [journyx].[dbo].[users] M ON S.modifier = M.id_user
ON T.id_time_rec COLLATE dataBase_default = S.id_time_rec COLLATE DATABASE_DEFAULT
WHEN MATCHED THEN UPDATE SET
T.time_amount = S.time_amount,
T.record_date = CONVERT(DATETIME, S.record_date),
T.company_name = dbo.usf_ProjectSplit(P.PName, '-', 1),
T.project_name = dbo.usf_ProjectSplit(P.PName, '-', 2),
T.comment = S.comment
WHEN NOT MATCHED
THEN INSERT
(

VALUES
