Calculation of FT avg share price

I have found average £ price of share is changed after selling some shares of my Novavax holdings .

I have purchased total 16 shares of Novavax at different time and rate . Then sold 9 of the shares on 5th Aug . After selling of 9 shares the Average £ share price changed from £131 to £114 for remaining 7 shares .

Wondering why average price changed on selling of partial shares of total holding ? Suddenly shows my appreciation on remaining share from 32% to 48%.

Details of transactions and screenshot of remaining shares holding .

P.S Alongs with me , many has raised for average stock price is native currency. This is essentially must future , without it cause sheer pain .
