Why are my interactive brokers commissions so expensive??

Hi so i was trading an etf on ibkr, its vwcg and its irish domiciled. im under the fixed pricing structure and its supposed to cost usd 0.005 per share minimum 1usd. i bought 2 shares of the etf at about 80usd per share and my commissions came to 5.33 usd. why is that so and does anyone have similiar problems as well also?? thanks
