Wrong costing Quantities

Hello All,

I have one FG which requires 5 units of same SFG which is phantom material to produce. these phantom material have its own sub components to produce for example A = 3 units, B= 3 Units and C= 5 Units

But when we are running the cost estimate for the material it is taking 5 times more of the materials under the phantom materials Like A=75, B= 75, and C= 125 units to produces 1 unit of FG i am not able to understand why this is happening can you help me out in this scenario.

Best Regards

Ravi
