Fasse - Some problems with translations and currency

Hi there,
i am using Fasse as a Shopify theme and like it so far. But there are a few problems.

Not everything is possible to translate. On the product page many translations are missing. It still says “add to cart”, “:truck: - Free shipping on orders over $50”, “Read more”
In Cart there are also some translations not working:
“Cart Total”, Shipping, Coupon Code

On the category-page the currency is dollar, although it should be Euro. If I click a product and go to the product page, the currency is in euro how it should be.
If I put it into cart, it changes to dollar again.
If I go to checkout it is euro again.

Any ideas how to solve the problems?
