Unable to delete ItemLoc for Warehouse in ORSIM v13.2.3

The ItemLoc message for Warehouse is getting processed into the staged_message table without any errors but the status in Item_Party table is still set as 'A'. Message_Data in staged message looks like below:

<?xml version="1.0" encoding="UTF-8"?>

<ItemLocRefDEO>

<ItemId>958756366</ItemId>

<ItemLocPhysRefDEOs>

  <ItemLocPhysRefDEO>

   <PhysicalLoc>8000</PhysicalLoc>

  </ItemLocPhysRefDEO>

</ItemLocPhysRefDEOs>

</ItemLocRefDEO>

Is there something missing in the above XML or is this a known issue with this version of ORSIM?

The same XML for deleting an ItemLoc for Store works absolutely fine.
