problem is shipping calculation

[Asifjalil99]

I have set weight & destination method. while calculating combine weight from the different seller, it shows less amount.
For ex : Seller 1 Items weight 0.1 kg
Seller 2 Weight 0.2 KG
Seller 3 Weight 0.3 KG
It takes combine of 0.5 kg and gives Rs.65
It should calculate 65+65+65

Preconditions

magento 2.3.0

Steps to reproduce

just enabled Seller ID attribute from admin
