The currency converter is not working well, it is not converting anything and I tried another converter app but the problem still there.
What is your website URL and what app are you using?
Are you using Shopify Payments and Shopify’s free app?

It also does this in a nice light way by injecting itself via JS rather than messing with your theme.
