Vault items "Awaiting Backup" not cleairing down below 3414

Hi, 

When  I open http://localhost/EnterpriseVault/usage.asp after backup DPM (trigger file method for clear itemsecured flag.), I follow the discussion https://goo.gl/7pO3ds

Active Archives	Total Items	Total Size (MB)	Awaiting Backup	SQL Server
4.412	40.443.514	8.683.625	3.414	EVSQLSVR.domain.local

I have check the table WatchFile under the Vaultstore DB and found that there are 3414 item with the value "1" for ItemSecured column.

USE [EVVSVaultStore_1]
SELECT * FROM [dbo].[WatchFile] 

I ran a Dtrace (set StorageFileWatch v y)  after a backup (set/clear backup mode, delete IgnoreArchiveBitTrigger.old and create the IgnoreArchiveBitTrigger.txt), log see attach file StoreageFileWatch.zip, For example I found this:

{CWatchFileTimer::CheckTriggerFileExists}|Trigger file G:\Enterprise Vault Stores\VaultStore Ptn3\PartitionSecuredNotification.xml not found so searching for .txt file

{CWatchFileTimer::CheckTriggerFileExists}|Trigger file G:\Enterprise Vault Stores\VaultStore Ptn3\IgnoreArchiveBitTrigger.txt found

CWatchFileScanRequest::ProcessUnsecuredItems Information: Total [0] unsecured savesets were found for VaultStoreIdentity = [1] and PartitionIdentity = [11].

{CWatchFileTimer::CheckTriggerFileExists}|PartitionSecuredDate = 2015-05-08 10:05:58 TZ

But for this partition I have 51 entry. 

I Run the DBCC SHOWCONTIG WITH ALL_INDEXES before and after of running (newly created Maintenance plan https://goo.gl/d1dUsC) and attach the file SHOWCONTIG_BeforeMain.zip and SHOWCONTIG_AfterMain.zip. 

Still no change.

How can I clear this 3414 files.

All this file where backup only with DPM, they are in difference Vault Partition and are from different dates.
