Wrong price display with the option

Hi

Your plugging is awesome , I am just in trouble about the additional price in the displayed subtotal price
in the end the total is correct , but the subtotal is showing for my case 4000.00€ instead of 40€

my link is below

https://french-national.com/produit/pass-bivouac-french-2022/
when you choose an option in the first selection ‘fromule French choisie’

If you can help me to correct this it will be wonderfull
