VC Model Folder Prefix append

Hi Guys,

when I deploy a VC model to the Portal the Folder ID Prefix gets appended with a 3 digit ID. What drives this ID? How can I prevent it?

com.myComp.myProduct.FJ9

com.myComp.myProduct.8HX

com.myComp.myProduct.H7E

com.myComp.myProduct.D55

com.myComp.myProduct.D3E

Thanks,

Michael
