Unable to derive tax on order line with multiple charge definition

Summary:

We are calculating total freight charge of an order and we will be adding overall freight charge to the “Freight” item line corresponding to charge definition "freight". In this case the "Freight" item will be having two charges. one with charge definition "sales" which will be defaulted from Price list and one with charge definition "freight" which will be defaulted from shipping charge list.

but on this scenario we are receiving the below error from vertex.
"The tax couldn't be calculated: VERTEX-0010-Error in applying pre-calculation Client extensions:Error in obtaining BIP external entity data:Duplicate key 300000118863595 (attempted merging values 2 and 3)"
