Wrong grand total when using Calculated Field [closed]

I have a simple pivot table, but I'm using Calculated Field values.

The raw data used for the pivot table is like a transaction log, as shown below:

DATE    | STOCK | QTY | PRICE | TOTAL---------------------------------------03/2023 |  AAPL |  1  |  100  | 10003/2023 |  AAPL |  2  |  120  | 24003/2023 |  GOOG |  2  |   60  | 12003/2023 |  GOOG |  3  |   80  | 240

The sheet also has the current price of a ticker with the GOOGLEFINANCE(..) function, as shown below:

TICKER | PRICE---------------- AAPL  | 158.28 GOOG  | 103.06

The pivot table groups the transactions by the ticker name, sums up the TOTAL per transaction QTY * PRICE, and shows the current value QTY * 'CURRENT PRICE'. The current price is a lookup to the current price table expressed as =VLOOKUP(STOCK,$K$7:$L$10,2, FALSE)*SUM(QTY) in the pivot table as a calculated field.

However, the Grand Total of the CURR POSITION column shows a wrong value. It shows $3,044.75 instead of $1,150.88. It should sum the VLOOKUP value, but it shows a different value.

How can I fix this?
