Stock Adjustment Entry at The time of Manufacturing Entry

I Posted a Manufacturing Entry from a BOM with a quantity of 15,000, which calculated:

Raw Material Consumption: Quantity 60 @ 155.17 = 9,310
Finished Goods: Quantity 15,000 @ 0.6207 = 9,310
This calculation seems correct,
but the system passed a Journal Entry for Stock Adjustment as:

Quantity 60 @ 439.66 = 26,379.6
26379.6 - 9310 = 17069 - Why system generate 17069 Adjustment.
I do not understand why this entry was passed. Kindly explain the concept of the Stock Adjustment Entry that was passed. Can anyone guide me on where I might be wrong?
