Subfolder subdomain adds both main language and second language

Hello

I have a shop with Shopify, which sells to multiple countries. I tried to setup the url for each language, but it looks like this: domain.com/en-fr

In the example above, English is the main language of the shop and French should be used whenever a visitor is from France. What is not desirable is that the url contains both EN and FR, and I do not seem to find anywhere to remove this (remove en). What I need this to look like is this: domain.com/fr

Is there any way to achieve this? Please also see the screenshot attached below:
