Item Import ends up with a Warning -> INV_IOI_ERR

 Hi

       We are on 11.5.10. I am trying to Import Items thro Item Inteface and using the Import Items Job.

The Item I am trying to Import is already defined in the Application, and I am trying to re-apply  the templates to MAster and all of the Child Orgs,

When I run the Impor Item Job, for couple of Child Orgs I am getting this Error

TRANSACTION ID : 78860179
ORGANIZATION ID : 394
TABLE NAME : MTL_SYSTEM_ITEMS_INTERFACE
COLUMN NAME : SEGMENTS
MESSAGE NAME : INV_IOI_ERR
ERROR MESSAGE : This combination of INVENTORY_ITEM_ID and ORGANIZATION_ID already exists within MT

Not sure what's this error.
